Kongsbak & Cohn was a company in Copenhague, Denmark. It made a box camera for roll film. The camera's design differed slightly from that of the average box camera: It had a crank for film advance, and the aperture selector lever and the metal fitting where it could snap in in three positions looked together like an anchor. Time or moment mode of the shutter had to be selected by moving a clockhand lever from "Z" to "M" position or vice versa. These characteristic levers were placed on the camera's front side, as was the company name-plate with the inscription Kongsbak & Cohn, Nygade 2 Skoubogade Kjobenhavn.
