OK I have a 135 Xenar in a late 60s/early 70s Synchro Compur (with the wide thick chrome shutter spring ring and smooth case). I was shooting today when it suddenly seized up. What happens is that I can only cock the shutter cock button about halfway and the shutter release "clicks" but the aperture doesn't open. I tried both ends of the shutter speeds, moving the MVX lever and the open aperture lever still works... I don't sense any play in the shutter cocking lever and can't get it to fully cock.
Any advice for a quick at-home fix? I am not exactly experienced at shutter repair.
And given that Carol at Flouots is ill and backlogged, is there a good repair person who could turn this around quickly?
