the front derailleur is the first generation
euclid, essentially a victory long cage mated
to a better clamp, useful for tight french
triple cranks like t.a. zephyr and mavic 637.
the rear i also have, and if you'd like side
by side scans, i'll send them to you. it
truly looks like a polished rally, down to
the by then obsolete limiting screws and
seem to have been made from the same mold.
one thing i will say, it has the longest
arm on any long cage derailleur i've ever
seen (much longer than the original rally
and anything more modern) and as such is
a shifting nightmare. my guess? it's the
first generation euclid.
