Photographer's number WD5990 The Ordnance QF 2-pounder (or simply "2 pounder gun") was a 40 mm (1.575 in) British anti-tank and vehicle-mounted gun, employed in the Second World War. It was actively used in the Battle of France and during the North Africa Campaign. As tanks became sufficiently armoured to stand up to its shots, it was gradually replaced by the 6-pounder, starting in 1942, though some remained in service until the end of the war. In its vehicle-mounted variant, the 2-pounder was also a common main gun on British tanks early in World War II, and was a typical main armament of armoured cars, such as the Daimler, throughout the war. This QF 2-pounder was not the same gun as the QF 2 pounder "pom-pom" gun extensively used by the Royal Navy as an anti-aircraft gun; they shared only the projectile weight of 2 pounds. Edenbridge is a town and civil parish in the Sevenoaks district of Kent, England. It is located on the Kent/Surrey border on the upper floodplain of the River Medway and gives its name to the latter's tributary, the River Eden.
