Hi Dale,
Short answer: I don't know. That being said... My '83 NOS Rossin came
with white leather Rossin straps. I'm changing the pedals and the ones on the "old" pedals are riveted on the ends instead of capped. I
bought white leather Campy leather straps for my '50 Locomotief in the mid-70s, and I figure some like that would work. In each case the
whites are pretty much white-white. The 70s ones are stamped with the
Campy logo in metallic blue and the 83s are stamped in silver. I'm also starting to build up another Rossin. I just bought a blue fade NOS frameset from David Lo in Antwerp. That's why I said blue. My '83
is an "Aero-Dynamics" and the new one is like it\u2014same lugs, drops, etc.\u2014only with conventional Columbus tubes, so I'm assuming its OT or
at worst KOF, and building it up with the same NOS components.
Regards
Mark
