One thing that says maybe respray to me are the 3 top tube cable guides. Those are generally found on frames with the later forks, and on Supers there are usually 2 of them rather than 3. Also, those guides generally appear later than the use of the shifter braze-ons, which your frame lacks - i.e. chronologically out of sequence from what I would expect. Notice I'm qualifying my statements because, well, it's a Colnago. I agree that the lugs look like non-Super (or Mexico) type, i.e. missing the little scalloped bit.

______________________________________________________________________________ "What made me wonder about the frame repair is that there doesn't appear to be any evidence of a respray. For instance in places where it has been scratched, or places you might expect overspray (steerer, inside ST, BB etc). Perhaps it was totally shot blasted before being refinished though.
Thanks for the info everyone,
