This is a pretty good link for Campy NR/SR stuff, but doesn't cover the newer ones:

Thanks, Pars; I came across that link myself while trying to figure out what I had. The spindle measures 111mm, which may end up being too short for this project anyway. I'll have to check the chain line once I get everything mocked up. I'm not worried about everything being original, but having the chainrings too close will mean I have to go shopping again. That would be a shame, as the bearing surfaces on this one look really nice.

I suppose I may be able to slip a spacer between the fixed cup and the BB shell.
