Originally dating from 1904, the gun and carriage of the 60 pdr Gun were redesigned by Vickers Armstrong in 1918. The Mark 2 Gun on Carriage Mark 4 became the standard medium gun but by 1939 was obsolescent. It was to have been replaced by the 4.5 and 5.5 inch Guns but in their absence it had to continue in service. It was last used in action in the Desert Campaign, notably by the Australians at Tobruk. It was retained in Britain as a training equipment until late 1944.
