This is a camera from the 1930’s, the production of the 515/2 started in about 1933, this is I think a latter model due to its lens.
The camera takes 120 film and produces 8 6x9cm images.
It is well engineered and bellows are in excellent condition. These cameras were made of quality materials, both bellows and shutter in these models are often workable, not something that is always the case in post 1945 examples.
In its day this was a basic model. It produces good results but is a little limited.
