Broken record time. :-)
One word, Benjamin: Sutherland's.
(Seriously - the Fifth Edition is probably he best for 'splaining all the Campagnolo loose-bearing BB stuff). eBay is about the worst possible 'source' of Campagnolo BB information on the planet, imo. About 50-75% of vintage Campagnolo BB items for sale there are incorrectly described in some way or another.
Yes, Record Pista always used thin cups - Record triples too. Only Nuovo Record double BBs used the thick cups (and then later, SR doubles, but the individual parts do not interchange between NR and SR doubles). The thick cups were what was 'Nuovo' about a Nuovo Record BB. (And while we're on the subject, the only things that were Nuovo Record in a 'full NR group' were the BB and the rear derailleur. Nuttin' else, although the headset boxes were sometimes marked 'Nuovo Record' even though the parts didn't change).
Also, the difference between thick- and thin-walled cups vis-à-vis bearing spacing is 5 mm, so your Pista BB project must have been very close. Check the width of your shell - maybe it's a bit wider than 68 mm, or you used bearings that are less than 1/4" in size?
You can also take a look at the Bottom Bracket page on my website, although it doesn't explain any of the OT later stuff like Sutherland's does.

Anybody know where there is a gallery/list of all the differences in Campagnolo bottom brackets.
I have a bunch of BB's that dont all seem quite right.
I am getting a little confused on thin and thick cup .
i was just using ebay to try and ID better and im getting more variations -same spindle but ones being sold w/ thick cups and another w/ thin.Some dont look quite right
I recently got a paramount pista that had a 68 mm shell- so when i put 68 pista bb together , it felt as though the cups should have been thicker -the adjustable cup went in so far that there was not much thread left for a lockring
Pistas always thin cup?
What about the indent in the outside face of a fixed cup?
When was Brev. Inter added above the world logo spindles?
Ive also had few spindles that have line(hash marks) on the ends of the spindles -are these older tooling marks?
I hope that all makes sense , im sure someone has put together a comprehensive BB ID guide at least for their own person.
what goes with what?
Thanks for helping me sort my bb box out
