<p>I acquired this 1940's Robot Luftwaffen-Eigentum rangefinder camera and I have a question on how do I adjust the focus on the rangefinder with this camera? I can't seem to find any knobs or dials to bring the view finder into focus. There is a small knurled wheel just about where your right thumb rests on the camera. But turning the wheel doesn't seem to do anything with the focus. It's not that I am going to use the camera but I'm curious if any one knows the answer to adjusting the rangefinder. </p>
