I picked up a Honeywell Pentax H3 for cheap a few years back and I had an issue with the mirror sticking up. Well, I solved that problem only to create another, I have jammed the film advance while dry firing the camera to work the lubrication in. The rewind button is sticking in as well. The film advance worked great earlier so I am thinking something got mis- aligned somewhere along the way. Any experience with this problem?
