Developed under Royal Navy sponsorship just prior to World War I, this gun was widely used by both the Navy and the Army and was employed to protect many British cities during that conflict. First mounted afloat on HMS Iron Duke and subsequently used on most major warships and on some submarines. Replaced in the 1920s by the 4\"\/45 (10.2 cm) Mark V on larger warships.\u003cbr\u003e\u003cbr\u003eDuring World War II this weapon was used on many destroyers in place of a set of torpedo tubes as well as on small warships and submarines.\u003cbr\u003e\u003cbr\u003eThe Mark I consisted of A tube, full length wire, jacket, breech ring, and a vertical sliding breech-block with semi-automatic action. Mark I* had different rifling. Mark IB had loose liner, full-length jacket and a removable breech ring. Mark IC was similar to IB but differed in details of the loose liner. Mark IC* was given to four guns with a muzzle bush instead of a loose liner sealing ring. There was apparently no Mark ID. Mark IE had a monobloc barrel and a screwed and shrunk breech ring. Mark SIE was a Mark IE but with the semi-automatic fittings removed, a balance weight added, a slightly different chamber and some parts were made from stainless steel, probably to allow its use on submarines. Mark II had different breech ring lugs for mounting purposes and no semi-automatic gear. Mark III was an emergency First World War design with parallel screw breech block and a two motion breech mechanism. Mark IV was similar to the Mark III but used a Welin block with an Asbury breech mechanism. Mark IVA was given to two Mark IV guns converted to use a loose liner.

Developed under Royal Navy sponsorship just prior to World War I, this gun was widely used by both the Navy and the Army and was employed to protect many British cities during that conflict. First mounted afloat on HMS Iron Duke and subsequently used on most major warships and on some submarines. Replaced in the 1920s by the 4\"\/45 (10.2 cm) Mark V on larger warships.\u003cbr\u003e\u003cbr\u003eDuring World War II this weapon was used on many destroyers in place of a set of torpedo tubes as well as on small warships and submarines.\u003cbr\u003e\u003cbr\u003eThe Mark I consisted of A tube, full length wire, jacket, breech ring, and a vertical sliding breech-block with semi-automatic action. Mark I* had different rifling. Mark IB had loose liner, full-length jacket and a removable breech ring. Mark IC was similar to IB but differed in details of the loose liner. Mark IC* was given to four guns with a muzzle bush instead of a loose liner sealing ring. There was apparently no Mark ID. Mark IE had a monobloc barrel and a screwed and shrunk breech ring. Mark SIE was a Mark IE but with the semi-automatic fittings removed, a balance weight added, a slightly different chamber and some parts were made from stainless steel, probably to allow its use on submarines. Mark II had different breech ring lugs for mounting purposes and no semi-automatic gear. Mark III was an emergency First World War design with parallel screw breech block and a two motion breech mechanism. Mark IV was similar to the Mark III but used a Welin block with an Asbury breech mechanism. Mark IVA was given to two Mark IV guns converted to use a loose liner. All marks fired fixed ammunition.\u003cbr\u003e\u003cbr\u003eThe Navy had a total of 596 Mark I, 198 Mark II, 44 Mark III and 144 Mark IV in service. Of these, 553 Mark I, 186 Mark II, 27 Mark III and 111 Mark IV remained as of September 1939.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

The design of this weapon was largely based upon the 13.5\"\/45 (34.3 cm) Mark V and it was rushed into production, bypassing the normal - and lengthy - prototype stage. This shortened design cycle was approved by the Director of Naval Ordnance, Rear Admiral Archibald Moore, who staked his \"professional existence\" on its success. The reason for this rushed procedure was to allow what became the Queen Elizabeth class battleships to be armed with larger guns than would have otherwise been possible. Although their first warshots were for bombarding shore positions at Gallipoli in 1915, the value of these weapons was not truly shown until the Battle of Jutland (Skagerrak). In that battle, the British battleships with these guns were able to engage German battlecruisers at a range of 19,000 yards (17,400 m), which was beyond the maximum range of the guns on the German ships.\u003cbr\u003e\u003cbr\u003eBy the mid-1930s the Admiralty saw these guns as growing obsolete, as other nations had developed more powerful weapons, capable of longer ranges and firing heavier projectiles. Along with this, the ships carrying these guns were approaching twenty years of service and starting to show signs of wearing out. Inhibited by treaty restrictions from replacing the battleships, the British instead sought to rectify the situation by initiating a \"modernization\" program whereby the ships had major overhauls performed and had their weapons upgraded. There were two significant improvements made to these guns during the modernizations: 1) The upper elevation limit of the mountings was increased from 20 degrees up to 30 degrees, which raised their maximum range with 4crh projectiles from 23,700 yards up to 29,000 yards (21,670 m to 26,520 m), and 2) The projectiles were improved and a more streamlined ballistic cap (6crh) was fitted which increased the range still further to about 32,000 yards (29,260 m) at 30 degrees elevation. Thanks to these modifications, in July 1940 HMS Warspite made one of the longest hits ever scored by a naval gun on an enemy ship when she struck the Italian battleship Guilio Cesare at approximately 26,000 yards (23,770 m).\u003cbr\u003e\u003cbr\u003eThe rate at which these ships could be modernized was limited and by the start of World War II Malaya, Barham, Repulse and the five Royal Sovereign class battleships had not yet been upgraded. Royal Oak, Barham and Repulse were sunk early in the war, but the remaining unmodernized ships were given a \"Super Charge\" which consisted of the largest possible propellant charge that the guns and mountings could safely handle. These were issued starting in late 1941 and at the maximum elevation of 20 degrees allowed a range of 28,700 yards (26,240 m). However, from a study of the records, it would appear that no ship ever fired a shot using Super Charges, although they were used by the coastal artillery at Dover. Super Charges were not issued to ships with 30 degree mountings as the increased barrel wear and mounting stress was not considered to be acceptable. For this reason, sources which quote HMS Vanguard as having gun ranges in excess of 32,000 yards (29,260 m) are somewhat misleading, as such a range would have required the use of super charges, which she never carried.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

The design of this weapon was largely based upon the 13.5\"\/45 (34.3 cm) Mark V and it was rushed into production, bypassing the normal - and lengthy - prototype stage. This shortened design cycle was approved by the Director of Naval Ordnance, Rear Admiral Archibald Moore, who staked his \"professional existence\" on its success. The reason for this rushed procedure was to allow what became the Queen Elizabeth class battleships to be armed with larger guns than would have otherwise been possible. Although their first warshots were for bombarding shore positions at Gallipoli in 1915, the value of these weapons was not truly shown until the Battle of Jutland (Skagerrak). In that battle, the British battleships with these guns were able to engage German battlecruisers at a range of 19,000 yards (17,400 m), which was beyond the maximum range of the guns on the German ships.\u003cbr\u003e\u003cbr\u003eBy the mid-1930s the Admiralty saw these guns as growing obsolete, as other nations had developed more powerful weapons, capable of longer ranges and firing heavier projectiles. Along with this, the ships carrying these guns were approaching twenty years of service and starting to show signs of wearing out. Inhibited by treaty restrictions from replacing the battleships, the British instead sought to rectify the situation by initiating a \"modernization\" program whereby the ships had major overhauls performed and had their weapons upgraded. There were two significant improvements made to these guns during the modernizations: 1) The upper elevation limit of the mountings was increased from 20 degrees up to 30 degrees, which raised their maximum range with 4crh projectiles from 23,700 yards up to 29,000 yards (21,670 m to 26,520 m), and 2) The projectiles were improved and a more streamlined ballistic cap (6crh) was fitted which increased the range still further to about 32,000 yards (29,260 m) at 30 degrees elevation. Thanks to these modifications, in July 1940 HMS Warspite made one of the longest hits ever scored by a naval gun on an enemy ship when she struck the Italian battleship Guilio Cesare at approximately 26,000 yards (23,770 m).\u003cbr\u003e\u003cbr\u003eThe rate at which these ships could be modernized was limited and by the start of World War II Malaya, Barham, Repulse and the five Royal Sovereign class battleships had not yet been upgraded. Royal Oak, Barham and Repulse were sunk early in the war, but the remaining unmodernized ships were given a \"Super Charge\" which consisted of the largest possible propellant charge that the guns and mountings could safely handle. These were issued starting in late 1941 and at the maximum elevation of 20 degrees allowed a range of 28,700 yards (26,240 m). However, from a study of the records, it would appear that no ship ever fired a shot using Super Charges, although they were used by the coastal artillery at Dover. Super Charges were not issued to ships with 30 degree mountings as the increased barrel wear and mounting stress was not considered to be acceptable. For this reason, sources which quote HMS Vanguard as having gun ranges in excess of 32,000 yards (29,260 m) are somewhat misleading, as such a range would have required the use of super charges, which she never carried.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e*STOCKED ITEM\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"text-decoration: underline; color: #0094d5;\"\u003e\u003ca href=\"http:\/\/micromaster.co.nz\/pages\/about-our-products\" title=\"Micro Master about our products\" style=\"color: #0094d5; text-decoration: underline;\"\u003eSUPPORT REMOVAL, CLEANING \u0026amp; PAINTING GUIDE\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e \u003c\/p\u003e","brand":"Micro Master","offers":[{"title":"Default Title","offer_id":31373534756969,"sku":"MM0008P","price":24.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/3579\/6585\/products\/1_700-15_-MKI-QE-1493-BB-4.jpg?v=1651451747"},{"product_id":"1-144-royal-navy-4-45-10-2cm-qf-mkv-ha-mkiii-gun","title":"1\/144 Royal Navy 4\"\/45 (10.2cm) QF MKV HA MKIII","description":"\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003ePRODUCT DESCRIPTION\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 14px;\"\u003e1\/144 Scale Royal Navy 4\"\/45 (10.2cm) QF MKV HA MKIII Gun as used by the Royal Navy and Commonwealth Navies.

QF guns had a higher rate of fire than did BL guns, an important factor for ships intended to be used in short range battles with enemy destroyers. The Mark V was first introduced as a low angle weapon on HMS Arethusa in 1914 and it was later chosen for use as an AAA gun near the end of World War I.\u003cbr\u003e\u003cbr\u003eDuring the Battle of Heligoland Bight in 1914 HMS Arethusa lost the use of all of her 4\" (10.2 cm) guns for a time due to problems with the cartridge ejectors. Her crew was eventually able to restore all but two of these guns to action.\u003cbr\u003e\u003cbr\u003eUp until the late 1930s the Mark V was the main British long-range AA weapon and was fitted in a majority of capital ships and cruisers. Most ships fired fixed ammunition, but the World War I cruisers and \"V\" and \"W\" class destroyers fired separate ammunition. Still used in large numbers during World War II with many new guns being manufactured. Guns removed from capital ships and cruisers in the 1930s were reused on many warships during World War II, including all eight \"P\" and four \"O\" class destroyers. Also issued as star-shell guns in some Dido class cruisers and early \"Battle\" class destroyers.\u003cbr\u003e\u003cbr\u003eThe original Mark V was constructed of a tapered inner A tube, A tube, taper wound wire, full-length jacket and breech ring. Used a horizontal sliding breech block, opening to the right, with semi-automatic action. Mark V* had no inner A tube. An \"A\" added to either Mark V or Mark V* indicated a strengthened bolt actuating. Mark V** had a heavy autofretted loose liner with a muzzle bush on the jacket and a removable breech ring. This mod was used for repairing guns in 1937. Mark V*** differed in detail and had a sealing ring instead of a muzzle bush, and its liner could be changed on board. The Mark VB was the intended new loose liner gun, but none appear to have been completed. The final version, the Mark VC built during World War II, had a loose barrel, changeable on board, a shorter jacket, removable breech ring and sealing collar.

QF guns had a higher rate of fire than did BL guns, an important factor for ships intended to be used in short range battles with enemy destroyers. The Mark V was first introduced as a low angle weapon on HMS Arethusa in 1914 and it was later chosen for use as an AAA gun near the end of World War I.\u003cbr\u003e\u003cbr\u003eDuring the Battle of Heligoland Bight in 1914 HMS Arethusa lost the use of all of her 4\" (10.2 cm) guns for a time due to problems with the cartridge ejectors. Her crew was eventually able to restore all but two of these guns to action.\u003cbr\u003e\u003cbr\u003eUp until the late 1930s the Mark V was the main British long-range AA weapon and was fitted in a majority of capital ships and cruisers. Most ships fired fixed ammunition, but the World War I cruisers and \"V\" and \"W\" class destroyers fired separate ammunition. Still used in large numbers during World War II with many new guns being manufactured. Guns removed from capital ships and cruisers in the 1930s were reused on many warships during World War II, including all eight \"P\" and four \"O\" class destroyers. Also issued as star-shell guns in some Dido class cruisers and early \"Battle\" class destroyers.\u003cbr\u003e\u003cbr\u003eThe original Mark V was constructed of a tapered inner A tube, A tube, taper wound wire, full-length jacket and breech ring. Used a horizontal sliding breech block, opening to the right, with semi-automatic action. Mark V* had no inner A tube. An \"A\" added to either Mark V or Mark V* indicated a strengthened bolt actuating. Mark V** had a heavy autofretted loose liner with a muzzle bush on the jacket and a removable breech ring. This mod was used for repairing guns in 1937. Mark V*** differed in detail and had a sealing ring instead of a muzzle bush, and its liner could be changed on board. The Mark VB was the intended new loose liner gun, but none appear to have been completed. The final version, the Mark VC built during World War II, had a loose barrel, changeable on board, a shorter jacket, removable breech ring and sealing collar. Altogether 283 Mark VC and 554 earlier types were made for the Navy with about 107 additional guns being manufactured for the Army, where they were used as AA and coastal defense guns during World War I. Of these, 83 were later transferred to the Navy. Of the 637 earlier guns in naval service, 601 remained in 1939.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

This was a somewhat large caliber for a DP gun, but chosen because it was considered that this size would provide the maximum weight of shell that could still be manually handled by the average gun crew. Unfortunately, the original design of the gunhouse was cramped and the heavy projectile and cartridge cases resulted in a lower rate of fire than expected.

These problems were mainly the result of the light construction methods used on most Treaty-limited ships, which in this case allowed the bow to flex in heavy weather or during high-speed turns. This was rectified in the early ships by stiffening the bow section and by more careful attention to the detail fitting work required for installation of the mountings. Later ships had these modifications incorporated during their construction and no problems of this nature were encountered for these cruisers. It is also recorded that after the winter of 1941 the captains of the early ships \"handled them appropriately\" during heavy weather which also alleviated the problem. However, in 1950 HMS Euryalus had A turret permanently out of action due to problems with the roller path.\u003cbr\u003e\u003cbr\u003eThese mountings proved difficult to manufacture and the King George V battleships were given the highest priority of what guns and mountings were produced.

HMS Dido had her fifth turret installed during a refit late in 1941 at the Brooklyn Navy Yard, while HMS Bonaventure was sunk in March 1941 and HMS Phoebe remained an eight-gun cruiser.

The design of this weapon was largely based upon the 13.5\"\/45 (34.3 cm) Mark V and it was rushed into production, bypassing the normal - and lengthy - prototype stage. This shortened design cycle was approved by the Director of Naval Ordnance, Rear Admiral Archibald Moore, who staked his \"professional existence\" on its success. The reason for this rushed procedure was to allow what became the Queen Elizabeth class battleships to be armed with larger guns than would have otherwise been possible. Although their first warshots were for bombarding shore positions at Gallipoli in 1915, the value of these weapons was not truly shown until the Battle of Jutland (Skagerrak). In that battle, the British battleships with these guns were able to engage German battlecruisers at a range of 19,000 yards (17,400 m), which was beyond the maximum range of the guns on the German ships.\u003cbr\u003e\u003cbr\u003eBy the mid-1930s the Admiralty saw these guns as growing obsolete, as other nations had developed more powerful weapons, capable of longer ranges and firing heavier projectiles. Along with this, the ships carrying these guns were approaching twenty years of service and starting to show signs of wearing out. Inhibited by treaty restrictions from replacing the battleships, the British instead sought to rectify the situation by initiating a \"modernization\" program whereby the ships had major overhauls performed and had their weapons upgraded. There were two significant improvements made to these guns during the modernizations: 1) The upper elevation limit of the mountings was increased from 20 degrees up to 30 degrees, which raised their maximum range with 4crh projectiles from 23,700 yards up to 29,000 yards (21,670 m to 26,520 m), and 2) The projectiles were improved and a more streamlined ballistic cap (6crh) was fitted which increased the range still further to about 32,000 yards (29,260 m) at 30 degrees elevation. Thanks to these modifications, in July 1940 HMS Warspite made one of the longest hits ever scored by a naval gun on an enemy ship when she struck the Italian battleship Guilio Cesare at approximately 26,000 yards (23,770 m).\u003cbr\u003e\u003cbr\u003eThe rate at which these ships could be modernized was limited and by the start of World War II Malaya, Barham, Repulse and the five Royal Sovereign class battleships had not yet been upgraded. Royal Oak, Barham and Repulse were sunk early in the war, but the remaining unmodernized ships were given a \"Super Charge\" which consisted of the largest possible propellant charge that the guns and mountings could safely handle. These were issued starting in late 1941 and at the maximum elevation of 20 degrees allowed a range of 28,700 yards (26,240 m). However, from a study of the records, it would appear that no ship ever fired a shot using Super Charges, although they were used by the coastal artillery at Dover. Super Charges were not issued to ships with 30 degree mountings as the increased barrel wear and mounting stress was not considered to be acceptable. For this reason, sources which quote HMS Vanguard as having gun ranges in excess of 32,000 yards (29,260 m) are somewhat misleading, as such a range would have required the use of super charges, which she never carried.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e  \u003c\/span\u003e\n\u003cp\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"text-decoration: underline; color: #0094d5;\"\u003e\u003ca href=\"http:\/\/micromaster.co.nz\/pages\/about-our-products\" title=\"Micro Master about our products\" style=\"color: #0094d5; text-decoration: underline;\"\u003eSUPPORT REMOVAL, CLEANING \u0026amp; PAINTING GUIDE\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e \u003c\/p\u003e","brand":"Micro Master","offers":[{"title":"Default Title","offer_id":31373845069929,"sku":"MM0015P","price":30.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/3579\/6585\/files\/450-15_-MKI-MI-N-HMS-Vanguard-1_Hero-Camera_a.jpg?v=1696201674"},{"product_id":"1-144-royal-navy-12-pdr-12cwt-ha-la-mkix-mount","title":"1\/144 Royal Navy 12-pdr 12cwt HA\/LA MKIX Mount","description":"\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003ePRODUCT DESCRIPTION\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 14px;\"\u003e1\/144 Scale Royal Navy 12-pdr 12cwt HA\/LA MKIX Mount as used by the Royal Navy and Allied Navies.

Many small warships still carried these old guns during World War II and they were also used in coastal defense batteries.\u003cbr\u003e\u003cbr\u003eThe Mark I was a fairly complicated design of A tube, B tube, jacket and C hoop shrunk over the B tube\/jacket join. The Mark II was a First World War gun with a combined B tube and jacket while the Mark V was produced during the Second World War and had a monobloc barrel. Some 4,737 Mark I and IIs were built along with an additional 3,494 Mark Vs. Canada also built over 1,000 of these weapons, which were referred to as the \"Ogden 3-inch\" as they were manufactured at the Canadian Pacific Railway's Ogden shops in Calgary.\u003cbr\u003e\u003cbr\u003eThe Japanese guns were originally purchased directly from Elswick and Vickers but later ones were license-built copies.

Many small warships still carried these old guns during World War II and they were also used in coastal defense batteries.\u003cbr\u003e\u003cbr\u003eThe Mark I was a fairly complicated design of A tube, B tube, jacket and C hoop shrunk over the B tube\/jacket join. The Mark II was a First World War gun with a combined B tube and jacket while the Mark V was produced during the Second World War and had a monobloc barrel. Some 4,737 Mark I and IIs were built along with an additional 3,494 Mark Vs. Canada also built over 1,000 of these weapons, which were referred to as the \"Ogden 3-inch\" as they were manufactured at the Canadian Pacific Railway's Ogden shops in Calgary.\u003cbr\u003e\u003cbr\u003eThe Japanese guns were originally purchased directly from Elswick and Vickers but later ones were license-built copies. These guns were similar to or virtually identical to the British Mark I. Used as anti-torpedo boat guns on larger warships. Redesignated as 41st Year Type on 25 December 1908. Redesignated in centimeters on 5 October 1917. Although finally classified as 8 cm, the bore remained 3.0\" (7.62 cm).\u003cbr\u003e\u003cbr\u003eEarly Italian guns were purchased from Elswick. Nearly all of the later ones were built by Ansaldo under license to a design provided by Armstrong during World War I or to a modified design for anti-aircraft mountings.

Used as anti-torpedo boat guns on most small cruisers built prior to World War I. As did other nations, the British found that these small-caliber projectiles were too light to be effective and many guns were converted following World War I to sub-caliber training and saluting guns.

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e  \u003c\/span\u003e\n\u003cp\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"text-decoration: underline; color: #0094d5;\"\u003e\u003ca href=\"http:\/\/micromaster.co.nz\/pages\/about-our-products\" title=\"Micro Master about our products\" style=\"color: #0094d5; text-decoration: underline;\"\u003eSUPPORT REMOVAL, CLEANING \u0026amp; PAINTING GUIDE\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e \u003c\/p\u003e","brand":"Micro Master","offers":[{"title":"Default Title","offer_id":31374361624681,"sku":"MM0023P","price":20.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/3579\/6585\/products\/B9-96-20mm-Oerlikon-Twin-MKIX-Main-1.jpg?v=1606683554"},{"product_id":"1-144-royal-navy-twin-20mm-oerlikon-mkix-gun-0º-elevation","title":"1\/144 Royal Navy Twin 20mm Oerlikon MKIX (0º Elevation) x2","description":"\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003ePRODUCT DESCRIPTION\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 14px;\"\u003e1\/144 Scale Royal Navy Twin 20mm Oerlikon MKIX Guns (0º Elevation) x2 as used by the Royal Navy and Allied Navies.

Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license.

A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system.

The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system.

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings.

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breech block is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan style=\"color: brown;\" class=\"tagnamecolor\"\u003e\u003cspan style=\"color: mediumblue;\" class=\"tagcolor\"\u003e\u003c\/span\u003e\u003cspan style=\"color: mediumblue;\" class=\"tagcolor\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941.

A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e  \u003c\/span\u003e\n\u003cp\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"text-decoration: underline; color: #0094d5;\"\u003e\u003ca href=\"http:\/\/micromaster.co.nz\/pages\/about-our-products\" title=\"Micro Master about our products\" style=\"color: #0094d5; text-decoration: underline;\"\u003eSUPPORT REMOVAL, CLEANING \u0026amp; PAINTING GUIDE\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e \u003c\/p\u003e","brand":"Micro Master","offers":[{"title":"Default Title","offer_id":31374909112425,"sku":"MM0036P","price":11.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/3579\/6585\/products\/B9-144-20mm-Oerlikon-MKVIIA-Main-3.jpg?v=1574733823"},{"product_id":"1-144-royal-navy-20mm-oerlikon-mkviia-guns-45º-elevation-x2","title":"1\/144 Royal Navy 20mm Oerlikon MKVIIA (45º Elevation) x2","description":"\u003cspan style=\"font-size: 15px;\"\u003e\u003cstrong\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-style: normal; font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -moz-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003ePRODUCT DESCRIPTION\u003cbr\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003cp class=\"sectioncont collapsiblearea\"\u003e\u003cspan style=\"caret-color: #000000; color: #000000; font-family: DIN Next; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;\"\u003e\u003cspan style=\"font-size: 14px;\"\u003e1\/144 Scale Royal Navy 20mm Oerlikon MKVIIA Guns (45º Elevation) x2 as used by the Royal Navy and Allied Navies.

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license.

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939.

The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system.

This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs. The barrel does not recoil, the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by the explosion of the next round of ammunition.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

They rejected the Oerlikon Model 1934, but in 1938 the Admiralty informed Oerlikon that if they could raise the muzzle velocity and demonstrate that the weapon could be used and maintained by non-specialist personnel, such as fishermen and merchant seamen, then it would be acceptable. Oerlikon made the necessary changes and the first prototypes of the new design were delivered late in 1939. These were immediately accepted into service as the 20 mm Mark I and Britain placed large orders with Oerlikon and obtained a manufacturing license. However, only a few additional guns were delivered prior to the German occupation of France, which cut off the supply route. This is basically why so few British ships had Oerlikon guns during the early part of the war, with the official USN BuOrd history stating that the Royal Navy had only 100 Oerlikons at sea in November 1940.\u003cbr\u003e\u003cbr\u003eShortly before France fell, the British took advantage of their manufacturing license with Oerlikon to obtain a set of production drawings. These were brought back from Switzerland by Stewart Mitchell, who had previously been Inspector of Naval Ordnance Contracts at the Oerlikon factory in Zurich. Mitchell, together with the famous ordnance expert Charles Goodeve and with Cmdr. S.W. Roskill (then working in the Admiralty Staff Division and later the famous Capt. Roskill, author of \"The War at Sea\") set up a factory at Ruislip to produce Oerlikon guns. \"Considerable difficulties\" with equipment and labor had to be overcome before deliveries of the British version of this gun, designated as the 20 mm Mark II, began in the fall of 1941. In November 1941, the battleship HMS Duke of York was commissioned with six of these weapons, which I believe to have been the first warship to carry British-produced Oerlikon guns \"as completed.”\u003cbr\u003e\u003cbr\u003eIt is not specifically known how many guns were built by Britain and the Dominion nations, but the Mounting Appropriation Lists of September 1945 show about 55,000 guns in service in the British and Commonwealth navies. This total probably includes weapons built in the USA that were provided as a part of Lend-Lease or installed on those ships refitted in US shipyards. Some British Auxiliary ships still carried these weapons as late as 2006.\u003cbr\u003e\u003cbr\u003eThe Mark 1 was the original design by Oerlikon. A small number of this version were built in the USA as prototypes. The USA Mark 2 and the British Mark II were the first production versions manufactured in those countries. The differences from the Mark 1 were mainly in the arrangements of the buffer springs, although the USA Mark 2 also had cooling ribs and two locking slots. The USA Mark 3 was similar to the Mark 2 but had fewer cooling ribs and only one locking slot. The later USA Mark 4 was the most common version built in the USA and had a single, heavier buffer spring. This version was built to slightly different tolerances as it was redesigned using English measurement units rather than the metric units used on previous Marks. The Mark 4 Mod 4 had a fluted chamber which allowed easier ejection of the spent cartridge cases. The Mark 1 could be fired in single-shot mode, while all of the others could only be fired in automatic mode. All guns used a monobloc barrel and a horizontal sliding breech block mechanism.\u003cbr\u003e\u003cbr\u003eThese guns are open-breech, air-cooled and use a gas blow-back recoil system. This weapon has some unusual features not found in other automatic guns. When fired, the case pushes the breech back against the force of the barrel springs.

This was a somewhat large caliber for a DP gun, but chosen because it was considered that this size would provide the maximum weight of shell that could still be manually handled by the average gun crew. Unfortunately, the original design of the gunhouse was cramped and the heavy projectile and cartridge cases resulted in a lower rate of fire than expected. In addition, the slow elevating and training speeds of the mounts were found to be inadequate for engaging modern high-speed aircraft.\u003cbr\u003e\u003cbr\u003eThe later mountings designed for HMS Vanguard enjoyed a much improved RPC system and were coupled with the USN's outstanding Mark 37 fire control system which eliminated the manually-operated fuze-setters in the previous mountings, giving the gun crews a roomier working space. However, Vanguard did not see service until long after World War II had ended and she was destined never to fire her guns in anger.\u003cbr\u003e\u003cbr\u003e\"A\" turret in the early Dido class cruisers was prone to jamming with some thirteen separate incidents being reported during 1940-41, including that of HMS Bonaventure while engaging the German heavy cruiser Admiral Hipper in December 1940. These problems were mainly the result of the light construction methods used on most Treaty-limited ships, which in this case allowed the bow to flex in heavy weather or during high-speed turns. This was rectified in the early ships by stiffening the bow section and by more careful attention to the detail fitting work required for installation of the mountings. Later ships had these modifications incorporated during their construction and no problems of this nature were encountered for these cruisers. It is also recorded that after the winter of 1941 the captains of the early ships \"handled them appropriately\" during heavy weather which also alleviated the problem. However, in 1950 HMS Euryalus had A turret permanently out of action due to problems with the roller path.\u003cbr\u003e\u003cbr\u003eThese mountings proved difficult to manufacture and the King George V battleships were given the highest priority of what guns and mountings were produced. As a result, the Dido class cruisers HMS Charybdis and HMS Scylla were completed with eight 4.5\" (11.4 cm) guns and three other cruisers, including HMS Dido herself, were completed with only eight 5.25\" (13.4 cm) guns. HMS Dido had her fifth turret installed during a refit late in 1941 at the Brooklyn Navy Yard, while HMS Bonaventure was sunk in March 1941 and HMS Phoebe remained an eight-gun cruiser. The later Spartan class were designed from the start with eight guns.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

This weapon superseded the 4\"\/45 (10.2 cm) Mark V HA gun on new cruiser construction during the 1930s. In addition, many older cruisers and capital ships had their Mark V guns replaced with these more powerful weapons during refits. A popular weapon, production could not keep up with demand until late in the war, resulting in many ships being armed with older weapons.\u003cbr\u003e\u003cbr\u003eHMS Carlisle, a converted AA cruiser armed with these guns, shot down 11 aircraft during the war, the highest score among British cruisers. The Auxiliary AA ship Alynbank, also armed with these guns, shot down six aircraft.\u003cbr\u003e\u003cbr\u003eThese guns were noteworthy as having \"neither long barrel life nor particularly high accuracy\" - John Campbell. This was blamed on the use of projectiles with a too-short parallel section which led to poor centering at the muzzle.\u003cbr\u003e\u003cbr\u003eThe original Mark XVI had an A tube, jacket from muzzle to removable breech ring and used a down-sliding breech block. Guns could be operated in either Quick Firing (QF) or Semi-Automatic (SA) mode. In QF mode, the breech was manually opened after firing by moving a lever which also ejected the spent casing. In SA mode, the breech would open automatically after firing and eject the spent casing. During loading, the breech mechanism would partially close when the cartridge case rim hit the ejectors and then fully close when the loading tray was raised. The Mark XVI* was the most produced version and differed by having the A tube replaced by an autofretted loose barrel with a sealing collar at the front of the jacket. Worn-out Mark XVI guns when repaired were converted to the Mark XVI* standard.\u003cbr\u003e\u003cbr\u003eThe Mark XVII was designed for some \"County\" class cruisers with the intention of replacing two of their single 4\"\/45 (10.2 cm) Mark V mountings with twin mountings without exceeding the Treaty weight limits. This hair-splitting exercise was described as \"ridiculous punctiliousness\" by John Campbell. Twelve guns were manufactured, all of which were later converted back to the Mark XVI standard. The Mark XVIII was the original designation for an improved version of the Mark XVI but this was redesignated as the Mark XVI* before being accepted into service. The Mark XXI was a lighter version built to revised design rules with an autofretted monobloc barrel and removable breech ring.\u003cbr\u003e\u003cbr\u003eSome 2,555 Mark XVI and XVI* guns along with 238 Mark XXI guns were manufactured in Britain. Canada produced 504 Mark XVI* and 135 Mark XXI guns. Australia built a further 45 Mark XVI* guns.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

This weapon superseded the 4\"\/45 (10.2 cm) Mark V HA gun on new cruiser construction during the 1930s. In addition, many older cruisers and capital ships had their Mark V guns replaced with these more powerful weapons during refits. A popular weapon, production could not keep up with demand until late in the war, resulting in many ships being armed with older weapons.\u003cbr\u003e\u003cbr\u003eHMS Carlisle, a converted AA cruiser armed with these guns, shot down 11 aircraft during the war, the highest score among British cruisers. The Auxiliary AA ship Alynbank, also armed with these guns, shot down six aircraft.\u003cbr\u003e\u003cbr\u003eThese guns were noteworthy as having \"neither long barrel life nor particularly high accuracy\" - John Campbell. This was blamed on the use of projectiles with a too-short parallel section which led to poor centering at the muzzle.\u003cbr\u003e\u003cbr\u003eThe original Mark XVI had an A tube, jacket from muzzle to removable breech ring and used a down-sliding breech block. Guns could be operated in either Quick Firing (QF) or Semi-Automatic (SA) mode. In QF mode, the breech was manually opened after firing by moving a lever which also ejected the spent casing. In SA mode, the breech would open automatically after firing and eject the spent casing. During loading, the breech mechanism would partially close when the cartridge case rim hit the ejectors and then fully close when the loading tray was raised. The Mark XVI* was the most produced version and differed by having the A tube replaced by an autofretted loose barrel with a sealing collar at the front of the jacket. Worn-out Mark XVI guns when repaired were converted to the Mark XVI* standard.\u003cbr\u003e\u003cbr\u003eThe Mark XVII was designed for some \"County\" class cruisers with the intention of replacing two of their single 4\"\/45 (10.2 cm) Mark V mountings with twin mountings without exceeding the Treaty weight limits. This hair-splitting exercise was described as \"ridiculous punctiliousness\" by John Campbell. Twelve guns were manufactured, all of which were later converted back to the Mark XVI standard. The Mark XVIII was the original designation for an improved version of the Mark XVI but this was redesignated as the Mark XVI* before being accepted into service. The Mark XXI was a lighter version built to revised design rules with an autofretted monobloc barrel and removable breech ring.\u003cbr\u003e\u003cbr\u003eSome 2,555 Mark XVI and XVI* guns along with 238 Mark XXI guns were manufactured in Britain. Canada produced 504 Mark XVI* and 135 Mark XXI guns. Australia built a further 45 Mark XVI* guns.\u003c\/span\u003e\u003cspan class=\"tagnamecolor\" style=\"color: brown;\"\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003cspan class=\"tagcolor\" style=\"color: mediumblue;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"caret-color: #000000;

Initially, either the 4\" (10.2 cm) QF Mark V or the 4\" (10.2 cm) BL Mark VIII were to have been installed, but the first weapon was difficult to arrange for director firing and the second had a low rate of fire. The best features of both, the Mark V body and the Mark VIII breech mechanism, were combined to create the Mark IX.\u003cbr\u003e\u003cbr\u003eThe Repulse class battlecruisers used both single and triple mountings, with the latter mounting having the guns individually sleeved, an unusual feature for a secondary weapon. This mounting required a very large crew of 32 and, as it lacked power assist, proved to be quite cumbersome.\u003cbr\u003e\u003cbr\u003eDuring World War II, this weapon was used in single mountings on many corvettes as well as on numerous smaller ships including 1,200 on DEMS.\u003cbr\u003e\u003cbr\u003eMark IX was of wire wound construction with tapered inner A tube and jacket. Mark IX* differed in having no inner A tube.

Initially, either the 4\" (10.2 cm) QF Mark V or the 4\" (10.2 cm) BL Mark VIII were to have been installed, but the first weapon was difficult to arrange for director firing and the second had a low rate of fire. The best features of both, the Mark V body and the Mark VIII breech mechanism, were combined to create the Mark IX.\u003cbr\u003e\u003cbr\u003eThe Repulse class battlecruisers used both single and triple mountings, with the latter mounting having the guns individually sleeved, an unusual feature for a secondary weapon. This mounting required a very large crew of 32 and, as it lacked power assist, proved to be quite cumbersome.\u003cbr\u003e\u003cbr\u003eDuring World War II, this weapon was used in single mountings on many corvettes as well as on numerous smaller ships including 1,200 on DEMS.\u003cbr\u003e\u003cbr\u003eMark IX was of wire wound construction with tapered inner A tube and jacket. Mark IX* differed in having no inner A tube. Mark IX** was introduced to suit older manufacturing equipment at EOC and COW and had no inner A tube, a B tube and overlapping short jacket and an old-style step wire-winding method.
