In the following auction, the seller lists it as first generation Record front derailleur and distinguishes the derailleur as having chrome plated bronze parts. I am curious: how is this particular derailleur different than others from 1963-1968, most of which have the cable stop on them? And how is this particular one marked in such a way that the seller knows it is from 1963?
Please note, I am not questioning the validity of his statements, but I would like to know how this particular one is distinct from others that certainly look the same.
Thank you.
Cheers.
