I've added some photos of the complete Kopir set. The last two photos show the film cassette in its chamber and the internal batteries and lamps.
Manufactured by BelOMO, the Kopir uses 21 mm wide film, hence the cutter provided. The frame size is 18 x 24 mm. The lens is an Industar with a focal length of 30 mm and a maximum aperture of f/5.6 (The same lens as the Yolochka). The Kopir uses an internal photo-cell linked to the shutter for automatic exposure times. Film speeds are set by the dial on the front face (1st photo). The lever on the back, advances the film and cocks the shutter. The lamps are powered by three AA (A316) batteries.
