Correct me if I'm wrong, but I believe the C-Record BB used 11 7/32" balls. The Record Pista used 14 3/16".

No. The C-Record bottom bracket used 14 3/16" balls:

The Super Record Pista and Strada (road) cranks also used 14 3/16" balls. Record Pista used 11 1/4" balls.

If I had imagined it, I would have 10 complete bb in my parts stash, although brake block holders would have been a better investment.
