Question about a stuck shutter curtain on a Nikon F3

I was fixing an F3 for a client in Austin last week and the second curtain just froze halfway. I thought the whole gear train was shot, but after checking the service manual, I found a tiny bit of old lube had gummed up the pivot post. I cleaned it with a drop of naphtha on a cotton swab and it ran smooth. Anyone else run into this on the F3 or similar bodies?

Notice how often a small, simple fix solves what seems like a huge problem.

Did you check the governor assembly for old grease too? That's another common spot for that kind of hang-up.
