The first camera I ever had. It's a fixed focus lens, with a fixed (but unspecified) aperture and exposure time. It used a medium format film, large enough that you could make contact prints that were a reasonable size. There's a red window on the back that showed the film numbers written on the back of the negatives as you wound them along. The film was backed with opaque paper, so they couldn't get exposed through this window. The winding was manual, you could take multiple shots on top of each other (it had a simple leaf shutter), and it was up to you to wind the film properly. There was no rewinding, you simply wound the film from one spool to another, and took the exposed film off with the other spool, and swapped the now empty spindle over for the next film.
It's from the monochrome film era; though I did, once, use colour film with it. That didn't turn out too well, since colour film wasn't as tolerant about poor exposure as black and white film was. This camera would still work, though it'd need some repairs to prevent light leaks, and you might find it hard to get the film (127 type).
