I have one of the older roleicords that after advancing to "1" in the viewing window you press another small knob while depresssing a button on the film advance and the counter goes to 1. It counts fine but if you look in the viewing window(red) you'll see that after it stops at "2" (on the counter) the frame in the viewing window is not quite to 2 and it gets farther off from there and sometimes the advances stops way soon and then get overlapping frames or if you go farther then everthing is way off. Any clues? Is it worht taking apart? Or do I just ignore the auto counting film advance and use the frame viewing window?
