I would have to say this bike doesn't look like a Colnago to me. I think the forks probably are fairly early Colnago forks, but the frame has a whole lot of things wrong with it...
1) There should only be 2 cable guides on the top tube. I am yet to see a Colnago with 3 cable guides. Colnagos of the same age as your forks actually had no top tube cable guides.
2) No lug cutouts is a warning sign. Every Super I have ever seen has a trefoil cutout under the bottom bracket, and at least one other trefoil or "Colnago" stamped on it somewhere.
3) That "Colnago Super" decal on the top tube is in the wrong place. It should be on the chainstay. Early Supers didn't have this sticker. They had "COLNAGO" stamped into the chainstay. I'd say the bike has had a repaint to match the forks with the frame, and someone has bought a Colnago sticker set at some time, and slapped them on without regard to correct placing.
4) Those rounded lugs don't strike me as being Colnago-esque. A bit too pointy for Ernesto, in my opinion, and the headtube lugs also lack the "W" shaped curve typical of early 70s Colnago lugs. And it may be the picture, but I don't think Ernesto would have allowed a bike to leave the factory with such sloppy lug brazing on those headtube lugs.
I assume that the threading on both the bottom bracket and headset are actually Italian...
Sorry to tell you that. Hope you can get a refund, or else you didn't pay too much...
