Howdy everybody, I was out and about today and picked up a Leica IIIb rangefinder in pretty good shape, all functions seem to work as they should and the shutter curtain looks very good, there is a spot of leather that has come off on the front as well as one of the body screws on the front is missing, the lens is a Jupiter 35mm f/2.8, the camera looks quite well for its age, the shutter sounds pretty darn on, however, when I removed the lens, I noticed two of the lens mount screws are missing, is there a place to purchase screws to fit this camera, also, does anyone make a leather kit to replace the damaged leather? Another question, is there a good book that anyone can recommend that would explain the opperation of this camera, I have figured the shutter speeds out, but am confused about the dial on the front of the camera that has speed markings on it...any comments on the quality of the lens, I have heard various things about these lenses, but have never used one. All in all a very nice vintage camera, that looks good and sounds good, it was one of those once in a lifetime finds, it was at a yard sale, and I talked the guy down to $50 bucks for it, I figured it would be a nice little pocket camera for street shooting and such.. Thanks for any comments or information you can provide. R.
