Well,,, got it diagnosed over the weekend. Bad rack, and what feels like a really gummy shutter. Really can't cock it by hand without forcing. It's not over yet, but the trip to see the Wizzard is on hold for a bit. I'm good enought to do the rack replacement and timing using the notes on the Chris Sherlock page. So, it's looking like one of my many month projects. I may send the lens and shutter off by itself in the next couple of months if I can find a good rack.
