Have any of you got experience with repairing the rangefinder mechanism in a fuji GSW 645 (the 60mm lens, non-folder)? I've got the option to get one with a rangefinder that "sort of works" (it is very sluggish but eventually the split images reach the proper registration which appears to match the focus distance). If the rangefinder is sluggish like this, is it likely that all the components are functional but just require lubrication or a reseating or something? I've heard that parts are difficult to find for this camera, and I would like to get the rangefinder working. The rest of the camera is in great shape, so it would be a fine portable landscape camera for hyperfocal / scale focusing.
