Vickers .303 Mk.I.

The Vickers machine gun or Vickers gun is a water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts.[18] It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft.
