Any idea how much a typical or standard 1980s old-school race frame would weigh ? Something like a 56 cm, full 531 tubes, Campy dropouts etc ??

I have such a beast with 1980s components (Campy, Modolo, Cinelli etc.., but don't want to strip it down just to weigh it. It's noticably heavier than my CAAD8, running part Campy, Kyserium wheels, and other un-interesting parts.
