The Certo Box was made in Germany by Certo c.1935. It is a sheet metal box taking 6x9cm images on 120 roll film. The control below the lens sets aperture sizes of f11, f16 or f22.

There were two models, Model A (illustrated left) and the slightly less basic Model B.[1]

The Model B has a better, "Certomat" lens.
