picture of this weapon?
This weapon was imported from the British firm of Vickers and used as an AA MG on a few ships in the 1920s. Some small quantity of these guns were also built in Japan. This weapon was water-cooled and recoil operated.
This weapon had a low muzzle velocity and a short effective range. For that reason, these guns were replaced on most warships starting in 1935 by the Hotchkiss 13 mm gun.
Actual bore diameter was 0.303" (7.65 mm).
