Neat project! The QL17 was my first rangefinder as well as one of my first cameras. I sold mine to someone in the Netherlands who insisted on paying cash. I had my doubts but a week later I received an envelope containing crisp new US currency in the amount we agreed upon in the mail, so I sent him the camera. Wish I would have kept it but I have too many cameras anyway.

A great extension to this would be the dedicated flash for the QL17.
