WHY not?

Best indicators that this could very well be a Colnago are the two cables guides on the top tube (*very* Colnago!).
Other hints: characteristic red metallic color & chromed fork (resp. chrome fake on right chainstay) while still built with the older fork crown - it's very likely that this is no Mexico. Shifter cables below the BB, so it's not late 70s. Should be a 81/82 Super. I'm not sure, but I think I can see one of those small Colnago hooks on the top front lug.
Geometry fits; Campagnolo shifters, Record breaks and water bottle/holders, probably also cranks and headset; Rolls saddle, 100mm stem - todo muy typical for a Super of those years.

Maybe the old transfers "fell off" (no transparent overcoat on Colnagos of that vintage) and were renewed - just with a bit more "character" than the factory scheme .

I'd too ask the seller about it, but I'd be quite confident that this is not a fake (and I've seen LOTS of Colnago fakes).
