Jim, et al, I don't know where to find history on it, but those parts usually have date codes, and date codes for nearly all of our on-topic stuff, are deciphered at the wonderful parts dating page at Skip Echert's Trek web site:

Scroll on down, and see what's there. Hope this helps...

Is there a website or other resource showing Superbe Pro history? The smoother more aero stuff is, IIRC, post '83, but I was wondering how far back it goes, plus, I just got an older Superbe crank that looks more like a Campy NR, and I'm wondering how old it is.
Thanks,
