Sometimes you get lucky. After reading some tips on the web (shutter capping on FTbs seems to be a popular subject), I dropped a little lighter fluid onto the shafts where the curtains roll up on either side of the film chamber through the front, w/ the mirror up and the shutter on 'B'. Next, I took the bottom plate off and dropped a drop of lighter fluid onto what appeared to be the shutter bushings (observed by cocking the shutter and watching what turned). Then, I opened the back and put a drop of lighter fluid on the top and bottom of the take up spool. Not the last one that you thread the film leader into, but the toothed sprocket one right before that. I let the camera sit for a while after firing the shutter a few times, and now it's opening beautifully on 1/1000. The camera is immaculate inside, but it had sat up for a spell, and I suspect some of the lubricants dried out. I'll continue to test it for a week or so, then load some film in it and see what happens. At this point it looks fixed though.
