Having just acquired a GS645 with leaky bellows, I would be interested to know of any repair facilities in the UK which could carry out this work.

I have been in touch with Camera Bellows, and they need my old bellows as a pattern for the new - unfortunately I don't currently know where to start in disassembling the GS645!! I have disassembled (and reassembled) quite a few shutters/cameras in the past, but I really don't want to mess this one up!
