An Extremely Rare Williamson G-28 Hand-Held Observer's Gun Camera.

#1616. Circa late 1930's (mentioned in Williamson 1937 advertisement, but not pictured). Designed to look and operate similar to a Lewis Mk2 machine gun, this camera was loaded with film into a top, removable cassette and used in training to access the progress of a rear gunner. 'Cocking' the camera advances the film and on 'firing' it records the accuracy, or not, of the user on film. Features recesses for a battery and a bulb. Clockwork can be heard running after firing, but unable to check if fully operational. The film holder is loose and should lock in position via the two round knobs to the rear but even when fully home it can still be removed. The lens appears original but unable to check for completeness or operation. Shows wear commensurate with age, the metal parts are covered in a brown patina probably caused by being coated in grease or oil for protection. Maximum dimensions approx 56 x 27 x 15cms Weight 5kgs.
