It could easily command a little more than a pro becuase of its relative rarity. What a sweet ride! I had a '77 International and a '79 Pro. Still have most of the Campy parts here and there, but the frames are long gone.
The Nuovo REcord gruppo from the International is on a '79 Benotto frame with a pair of Modolos on it since the International had Wienmann center-pulls.
John E., Had the same year Bianchi Campione d'Itlaia. Was working in a shop part time and spending all my money on the product! That one was stolen while still pretty new.
