A friend showed me a Colnago he's recently inherited. It says "Colnago Super" on the chainstay. I wasn't really sure what to look for at the time, and the lighting was great, but it was a dark red metallic, chromed fork and dropouts (and maybe head tube lugs), round tubes, Columbus tubing badge. It had "Colnago" engraved/stamped at the top of the seat stays. I got the impression it was probably from the 1980's. It didn't have the best components - Shimano Exage brakes and mech, for example. Stronglight chainset, Campag downtube shifters. It wasn't mint - it looked like there was rust on rear brake cable along the top tube - possibly the cable guides.
He said he'd had a look online and thought it might be worth £1,000. I'm not sure it's worth as much as that (I'd probably have said around £500 given the components and condition, although it might polish up just fine).
I know it's hard to value without photos, but is there a typical price for this model, or does it vary wildly depending on model year, condition and components etc?
