After running about 10 or 12 rolls of Tri-X through this camera where it accurately detected the starting point of the film, the frame counter got stuck at "5" instead of resetting to "0". Since I was on vacation in Provence and had no tools, I had to revert to the Flexaret which I was carrying as a backup. When I returned home, I took off the right side panel and the counter immediately reset itself to "0. I reassembled the right side and was able to load a roll of film successfully. Since everything else on the camera seems to be working properly, I am reluctant to spend the money for a full CLA, especially since this part of the mechanism seems to be quite accessable. If the counter contiues to hang up like this, is it a simple fix?
