Just picked this beauty up and it's in really nice shape. The shutter sticks open at 1/15 and also stays open on bulb until the camera is advanced. The rest of the speeds seem to work OK but I haven't tried to test the speeds. I'm pretty sure this just needs a CLA but I'd like to find some reference material. Online tutorial or a .pdf download of the original repair manual. Did some web searches but haven't found anything. Does anyone here have some info or could at least point me in the right direction? This isn't my first camera I've had apart and I haven't had one yet I couldn't fix.
