nice bike anyway...only things that worry me are a DuraAce crank on a Campy spindle, that could be an issue. Plus just an oddity: you say it's 120mm rear spacing but the short dropouts have the PortaCatena holes which mean they date this frame to post 1978. I don't know if that's a Zeus built fork or just a Zeus crown, AFAIK Zeus was not a supplier of complete forks to other marques, but their frame bits were sold to and used by many others.
