No problem, Dan! But thanks for getting back to me on it. You know, the rangefinders on those C3s are pretty easy to repair, and non-invasively at that. (If a dummy like me can do it, anybody can!) The round viewer lenses pop right out for cleaning. You can use a couple of tiny screwdrivers to get the screw on top loose to adjust the rangefinder focus with a couple of small screws inside.
