This vintage Agfa Karat IV 35mm rangefinder camera was made in Germany. It comes with the original leather case and user guide booklet. 

It also comes with a VERY RARE Solagon 50mm f/2.0 lens. Seriously - good luck finding one of those! 

The film winder does not appear to work... although I am not an expert in vintage 35mm cameras so maybe I'm doing something wrong?

It was purchased by my father while he was in the Army and stationed in Germany during the 1950s. I've included 3 photos from the era showing him or a friend with this very camera and its leather case as indicated by a red arrow. 

Very cool piece of vintage camera history!
