WILLIAMSON TYPE 29 REPLICA VICKERS K CINE MACHINE-GUN
The Vickers K Machine-gun was originally used by the Royal Air Force in aircraft as it had a high rate of fire which made it suitable for shooting down aircraft. In July 1939 the G45 camera gun, designed and manufactured by the Williamson Co. of London and Reading, was issued to armament schools and fighter units.
Williamson also supplied a replica Vickers K gun, the Type 29, with a camera mount and reflector sight bracket for use with the G45 cine gun camera. The G45 camera used 16 mm orthochromatic film supplied in 7.62 m (25 ft) lengths. Frame speeds could be regulated to 16, 18 or 20 per second, these speeds corresponding to the rates of fire of the Lewis, Vickers K and Browning machine-guns.
