Purma Special 1937-1951.

Description - The Purma Special camera has a plastic body with metal parts and a fixed lens aperture of f6.3 giving a focal length of 10 feet to infinity. This camera was rather special due to the novel innovation of the focal-plane shutter mechanism using gravity to offer three shutter speeds, 1/25 (Slow), 1/50 (Medium) and 1/450 (Fast). There is no shutter speed selector on the camera as the shutter speed is selected by the way the camera is held and used to take photos, and for this reason the film format was square. Fast shutter speed is selected by holding the camera vertically with the wind knob in the up position. Medium shutter speed is selected by holding the camera horizontally, and Slow shutter speed is selected by holding the camera vertically with the wind knob in the down position. The words ‘Fast’ and ‘Slow’ are moulded into the Bakelite on either side of the viewfinder as a reminder in which way to hold the camera; and the Purma Special would take sixteen square photographs on 127 film.

History - The Purma Special, produced by Purma Cameras Ltd of London between 1937 and 1951, was sold by R. F. Hunter of London, England.
