RAF WWII Spitfire Aircraft G45 Gun Camera.

RAF WWII SPITFIRE AIRCRAFT G45 GUN CAMERA.
The G45 gun camera was used throughout WWII by British fighter units and armament schools from 1939 onwards (including by the RNZAF). It was designed and manufactured by the Williamson company of London and Reading and was developed from the G42B. It used 16 mm orthochromatic film supplied in 25 ft lengths with a frame speed of 16, 18 or 20 per second, these corresponding to the rates of fire of the Lewis, Vickers K and Browning machine guns. The G45 was fitted in the wing as standard on Fighter Command aircraft (Spitfire and Hurricanes). It was controlled by an electrical switch operated by the gun-firing pneumatic system.
