Internal view. This 35mm camera with epicyclic movement was made by the British engineer J A Prestwich. Prestwich was one of the first manufacturers of sturdy, wooden-cased cine cameras, developing mechanical details such as epicycle intermittent motion and, in 1899, the detatchable film magazine. In 1896 Prestwich collaborated with William Friese-Greene (1855-1921), to produce a double projector, which claimed to remove flicker from the projected image.
