There was a CR thread on this very subject several weeks ago. Some said that the holes are for grease injection. I said that grease guns were not common in the bike world before MTB-things like Grease Guard, though several people corected me. Okay, so they had grease guns in their toolboxes before everyone else. I still say that Campy put the holes in the caps and shell so that oil could be dripped in to loosen up old grease. That's what I was told by a couple of reliable sources "back in the day." Of course, the holes can also be used for oil-only lube purposes. This was once more common than today, especially on the track. I've heard the truly hard-core would also remove one ball bearing, in some sort of (misguided?) attempt to further reduce friction.

OK, ya'll convinced me. I'll grease the damn things. BUT, why then do so many vintage hubsets have oil holes?
