Just wanted to put up a pointer to this excellent site I've found with instructions for disassembly and adjustment of various old shutters.


Using the instructions for Compur-Rapid shutters I could figure out enough to clean a Synchro-Compur shutter that's been troublesome for a long time, and it seems to have worked pretty well!

Also includes instructions for adjustment of many old cameras, largely 35mm rangefinder types.
