Item is a specialty camera manufactured by CAMBO B.V at Kampen in the Netherlands. Designed specifically for passport photographs, the cameras took 4 instant images at once. The front plate holds four identical Cambonar lenses, all with apertures from f 8. to f 32, and a focal length of 125mm. The individual or (optionally )coupled shutters allow exposures from : B, 1/50, and 1/ 100 of a second. The back with a fine mat screen allows focusing by moving the lens board with all 4 lenses by a precise rack and pinion drive, which can be arrested by a separate screw. The mat screen can be lifted to allow inserting of a standard Polaroid film holder for 4x5 professional film. The photographer could expose all four lenses together or every one separately. The individual fields on the back measure each 55 x59 mm. A flash sync terminal and a socket for a cable release were included.
