I have one that I have managed to strip and sort all the sticky bushes that jam the shutter up. It is a bit of a fiddly exercise removing the leatherette and tracking the shims etc. but it is working nearly except in Auto. Stripping out and cleaning the mirror box means removing wires and working around the switch arrangements inside and it could be that the air spacing on the switch has got slightly moved but I am not sure. Basically the camera powers up winds and the shutter releases. the main issue is that the metering seems to be operating in manual mode, i.e. with the up down buttons when in Auto or Manual mode. I was wondering if anybody else out there has been through this process themselves and has experience that they could share? Thanks Phil.
