C-Record BBs 1985-90 used 3/16" balls 14 per cage, same as Super Record Titanium. Later C-Record used 11 7/32". Virtually all on-topic Campagnolo BBs aside from SR Ti use 11 1/4" balls. No parts using different ball sizes interchange. I'm not sure about Victory/Triomphe though, those might sometimes interchange with older stuff and Victory at least looks to me like full Record quality.

As (almost) always, a trip to Sutherland's Fifth (as opposed to Beethoven's!) will sort this out. Pages 3-30 and 3-31 (my two personal favorites, btw), to be specific. Kurt is correct (but don't forget the weird one-year of 1960s Record that used sfere da 3/16"), and I'll add that Croce, Victory, Triomphe, GS, Chorus, Athena, Xenon, Euclid, Centaur, and Olympus (whew!) all used 1/4" bearings. Be careful about 'thick' vs. 'thin' bearing spacing on the spindles and cups, though. Croce used thick (rifled) steel cups, as did Nouvo Record, and the ATB stuff was effectively like a thick-cup BB in most (but not all, of course) cases. Way too much complexity!!
