Help identify this Campy crankset

They have the "C" diamond stamp on the chainrings and a "93" in a box on the back of the crank arms.

Any ideas? Can't tell if they're Athena, Croce D'Aune, or Record. Don't think they're Chorus.

I believe it's C-Record era Athena. Pretty sure that Record has one arm of the spider hidden behind the crank arm, but it could also be Croce D'Aune from the same era.

That would also be my best guess,^^^ since the Chorus version has a sort of snout at the dustcap/puller opening.

They have the one key release, so they are Croce d'aune or 90s Chorus (the Croce d'aune chainset became Chorus).

Did Croce D'aune ever have pinned chainrings? Anyone know what year they started doing that? I can't find it in any of the catalogs online.

Anyone know what the number in the box stamped on the back of the crank arms means?

It's a date code. If it actually means '1993' then that would make them Chorus since Croce d'Aune didn't exist then. I'm with the others that it's either Chorus or CdA...the CdA crank became Chorus at some point and Athena didn't have the one-key extractor.

Starting in 1973 the crank arms have a code consisting of a diamond (1970's) or circle (1980's) with a number in the center denoting the last digit of the year of manufacture, and then in 1985-9 with square and number in the center: 11 = 1985, 21 = 1986, 31 = 1987, 41 = 1988, 51 = 1989 plus some other examples.
