Well, after looking at my catalogs, I think I have some answers for my question.

You have one ring representing each of these two applications.
The bottom ring is C-Record. The top ring
is not Super Record. SR is 144BCD, this one is 135BCD. The ring in question (the top one)
does fit the C-Record crank I have. Looking at one of my Campy catalogs, I see now that the ring in question is probably Croce or Athena, as concluded by John E. Even though I cannot use the ring, I still got a 42 that I can use out of the deal. Hey Marty...want a 52 for your Croce on your Reus?
