I recently purchased an Italian bicycle that dates between 1962-1965. I'm trying to use period-correct components to restore the bicycle. It came with a Campagnolo headset that may or may not be period correct. It looks like a Super Record headset but both the top head race and lower head cup have drilled holes.I need your expert opinion on:
1) Whether you are familiar with the headset I described above; 2) The dating of the 3rd and 4th generation Record headset; 3) The dating of a Record headset I have with the lettering <c> on the fork crown race.
Thanks, Lewis Ting Chicago, Illinois
PS. Anyone willing to part with a 151 crankset (without raised pedal
holes),
please contact me.
