Klapp-type camera consisting of two parts:
- the original front part with the Goerz lens alone, the frosted glass. The fully open curtain system is no longer functional.
- The rear part is connected in place of the frosted glass, which extends the darkroom, and the frosted glass is placed at the end. A shutter Bausch & Lomb has been fitted to the lens as an accessory for taking pictures (the attachment is provided on the ring of the lens).
