Vintage 1936 Boltar-Bolavit German Subminiature Spy Camera with 35 mm Film in it. It does have a 40 mm lens. I really don't know much about vintage cameras. This was purchased at an estate sale. The camera does appear in good shape for its age. It also still has old 35mm Film in it. From other cameras like this it appears this camera is missing on theback the circular back lens. Also on the front the silver metal advance lever appears to have broken off. Also there is no camera bag.(Please see all pictures). Hopefully I have the correct terminology for the items missing. ** Shelf C2.
