> Please help establish the vintage of the following: Record rear derailleur, chrome plated, all steel, says patent Campagnolo, no date <
Probably 1963 to 1968. Are the pulleys round steel without teeth, or are
the plastic with high teeth (or other)?
> Record (or NR) front derailleur,aluminum body with an integral cable stop on the bottom, cage like early NR <
Probably 1958-ish to 1969-ish.
> Record clamp on shifters, the levers are thin without the extra material near the pivot point <
What do you mean by "thinned"?
> NR cranks with a raised boss around the hole for the pedal spindle, say only 170 strada; cahinrings 54/47 (wow) <
About 1962-ish (are there dustcap behind the pedal holes?) to about 1969.
If all these parts are from the same bike, then I'd say 1963 to 1969. Derailleur pulleys might narrow it down to pre or post-1967.
