to xiaoman 1 : the earlier px10s used Nervex Pro lugs, in 72 they switched to Nervex "Duobois"
in 73 they went back to Nervex Pro. As to the OPs idea of finding a bare frame and building it up with Campy
It's been done many many times. I have a much cooler idea. build that bare frame with the best the
French had to offer just before they went under around 198?.Jubile derailleurs, TA Tevano cranks,
TA pedals or Rodger Peele pedals, Mafac sidepulls or CLB, Ideale 2002 seat. It will be lighter and prettier!!!
