(See Gallery Non-Gallery Pictures) I bought this camera for $30 at a shop recently. It is made by Noris (120 film) and has some nice and unusual features. the lens is a Schneider-Kreuznach Xenar f2.8. The shutter is a Compur. The strange thing is the back with it's 4 film number viewing openings. They all open at once with the lever. I have never seen something like this. It is only a bit bigger than my Kodak Retina Ia.
I am hoping someone may have some information on why the back is like this. My searches turn up only projectors under the Noris name. The lens is clear and the shutter works. I am going to try it out.
