$4-600 but it needs some 'presentation' work.
Colnago framesets have a minimum inherent value. Yours appears to be good condition but it has no decals and a full chrome fork. Has it been repainted?
Super Record crankset, Campy SL pedals, NR seatpost, GS brakes, NR derailleurs. Quite the combination of parts.
Seriously....get rid of the granny seat and put a proper racing piece on there. The Concor Profile would work.
