	GUN STRUCTURES
		QF breeches also had 'extractors' to eject the empty cartridge case when the breech was opened.
		By WW2 the trigger action for QF guns was 'fired' by a manually operated firing lever mounted on the cradle with mechanical linkages to the firing mechanism inside the breech block, the firing mechanism was cocked and fired in a single action.
		The buffer's oil also had to be kept topped-up, either by a gravity fed tank on the ordnance or by a tank in the cradle, or in the case of the 25-pdr, a replenisher cylinder parallel to the buffer and recuperator cylinders.

	Ordnance QF 17 pounder - Wikipedia, the free encyclopedia
		The Ordnance QF 17-pounder (or just 17-pdr) was a 76.2 mm gun developed by the United Kingdom during World War II.
		Initially the HE shell that was developed for the 17 pdr lacked power.
		The British also converted some of their M10 Wolverines removing the 3-inch (76 mm) cannon and replaced it with the 17-pdr as well; the resulting vehicles were called Achilles or just 17 pdr M10.

		The Ordnance QF 6-pounder 7 cwt, or just "6 pdr", was a British 57 mm gun, their primary anti-tank gun during the middle of World War II, as well as the main armament for a number of tanks.
		The first attempt was an 8 pdr of 59 calibers, but this version proved too heavy to be used in the same role as the 6 pdr.
		Instead the 6 pounder was followed into service by the next generation British anti-tank gun, the 17 pounder which aside from a small batch in 1942 to fight the Tigers, came into use from 1943.

	Tanknet -> Damn The 25 Pdr!
		The 18 pdr is considered approximately equal in effectiveness to French and US 75mms (since they were they same), but WW2 US 75mm shell carried at least as much HE as the 25 pdr despite the overall shell weight being 40% less.
		Picky> IIRC, the 25 pdr is 87.6mm caliber.
		The 25 pdr MkI was the 18 pdr MkIV with a new 25 pdr barrel.

		The basilisk was a large cannon capable of firing a shot of 160 pdr.
		Guns are a major component of a fort and in particular cases the forts were built on purpose to accommodate a type of gun (Rinella and Cambridge Batteries).
		The most common guns were 24 pdr and many of them were expenisve bronze cannons which today are found on the front of important buildings such as Palaces or Churches.

	Clan USMC "BIA Squad" -- semper fidelis
		The U.S. Army Ordnance Department designed the M4 medium tank with a 75 mm gun in a traversing turret on the chassis shared with the interim M3 Medium Tank known as "Lee".
		The British devised a late-WWII post-production conversion called the Firefly that mounted the even more potent British QF 17 pounder (76.2 mm) anti-tank gun in the standard turret by moving the radio to a new bustle on the turret rear and by turning the long-recoiling AT gun on its side.
		The British offered the 17 pounder with its significant armour penetration but a significant initial (later rectified) HE shortcoming to the Americans but the US Ordnance Department was working on a 90 mm tank gun and declined.

	25 Pounder
		From about the year 1700 until the adoption by the British of the metric system of measurement in ordnance manufacture, field guns have been designated by the weight of their standard projectile.
		First produced as the QF 18-pr Mark 4 in 1918 this gun was converted in 1935 to 25-pr by fitting a loose liner of 3.45-inch (87.6-mm) calibre.
		The strength of the carriage was amply demonstrated in 1943 when the first QF 17-pr anti-tank guns were mounted upon it; it easily stood up to the much more powerful piece.

	Definitions and Information about Naval Guns - Part 1
		This separation into BL and QF categories was carried into the designation system, with BL and QF guns of the same caliber being enumerated into different numeric series.
		The bore size was followed by the BL or QF designation and a Mark number using Latin numbers, sometimes followed with one or more asterisks or stars which indicated minor modifications to the original design.
		For example, the designation 4-in QF Mark XVI* meant a cartridge gun firing a 4 inch (10.2 cm) projectile, with the design being the sixteenth gun in the 4 inch QF series and having had one minor modification to the original design.

	AMMUNITION
		The term 'QF' originated with the late 19th century introduction of field guns firing rounds comprising propellant packed in brass cartridges (with a shell fitted to their mouth) that were loaded through the breech with the cartridge case providing obturation.
		The largest calibre QF ordnance used by British field artillery was the 4.5-inch Howitzer introduced in the first years of the 20th century and remaining in service until late in WW2.
		However, its flame was not as strong as that from a QF primer and it had a lot further to travel, so the bottom of the base charge bag had a built-in gunpowder igniter that in turn produced a flame powerful enough to ignite and explode the propellant.

		The suggestion that medium-caliber, quick-firing guns were more amenable to spotting corrections than large guns, because in the case of the latter the target would move too far in the interval between shots for such adjustments to be effective.
		The Bureau of Ordnance believed that the 6-inch would have a rate of fire three to five times greater than that of the heavier gun.

		The data on Japanese ordnance manufacture and the role of the British involvement in this are very disparate and scattered in contemporary and modern secondary sources.
		The section on Japanese Ordnance factories by Jane's assessment of the fighting ships of the world's navies states that guns were manufactured at the Kure Naval Yard and by the Muroran Steel Works, Hokkaido, which was licensed to built Armstrong's and Vickers types of guns.
		This vessel was equipped, among others, with 8 6-inch-45 cal QF guns, which were most likely copies of British guns.

		The first of these was the Maxim one-pounder (1 pdr) of the late 19th Century in 37x94R calibre, named for the weight of the shell.
		Within the jacket was a steel sleeve containing 28 grains of incendiary composition with a further 2 grains of QF composition held in the jacket tip.
		It used a long-recoil variant of the Maxim action, as did a scaled-up version, the 1 pdr Mark III in 37x69R calibre, which saw brief service with the RFC as an aircraft gun in WW1 (it is sometimes confused with the much larger 1 pdr "Pom pom").

		This allowed ammunition produced by any American or British ordnance manufacturer to be used with any weapon produced by either country, thus greatly simplifying the logistics problems of a world-wide war.
		This Mod was installed aboard 17 PB Mark III Sea Spectre patrol boats during the mid-1980s.

		Total production of all Lee-Enfields is estimated at over 17 million rifles, making it the one of the most numerous military bolt-action rifles ever produced- second only to the Russian Mosin-Nagant M91/30, which was itself a contemporary design.
		When the US entered WWI, the P14 was standardized and modified by the US Ordnance Department and went into production in America as the M1917 Enfield, having been chambered for the standard US 30-06 cartridge, ultimately far surpassing the Springfield in total production.
		Contributing to the total was the arsenal at Ishapore in India, which continued to produce the Enfield in both.303 and 7.62 mm (NATO) (the 2A1) until the 1980s,the BSA factory at Shirley near Birmingham, and SAF Lithgow in Australia, who finally discontinued production of the SMLE Mk III* in 1950.
