Chromed head tube lugs were a common feature on Superissimo frames. The paint missing from the RH rear dropout looks like it uncovers a chrome finish. With "COLNAGO" cast into both sides of the bottom bracket would also suggest a Superissimo. On this frame I would pay little credence to the frame decal but, it you get the chance to remove the bottom bracket it would be nice to inspect the seat tube or down tube for signs of any helicoidal reinforcement bands. My guess is that they will be present suggesting Columbus SLX frame tubing.

Oh yeah, those head tube lugs from that era are my all time favourite Colnago lugs - just saying.

The old Campy Veloce gruppo is very nice but I don't really trust those beautifully sculptured seatposts as I have snapped one in the past.

I must admit that I really like this bike and I would be tempted to buy it also. The bottom headset race is a concern though - perhaps the wrong sized balls??
