we need a bit more information. "campi Components" does not tell us alot. how often hav you had some say a bike "Full Campagnolo" only to have the RD and shifters be Campi and the rest Ofmega and Modolo. ask the seller for a list of components.
I suspect the cranks could be Ofmega and the brakes Universal or Modolo. the decals with the 'flag' look '84ish -87 but the Piaggio decals were last used for the Bianchi USA bikes in '84 I believe.
