I've been trying to date an old campagnolo I received. just curious if anyone could help me out. Although I dont have pictures yet, I have the serial number (71 A 1197) and I know its late 70s. Like I said, pretty sure the frame itself is campagnolo: brake levers, gear shifters, etc. all have either "campagnolo brev" or "campagnolo nuovo record" on them.
appreciate any help as well as how much it may be worth
