Chuck,
What you have there is an early '70s Italvega Nuovo Record frameset, except for the incorrect fork. I happen to have the complete bike, that's how I know. Yes, it is Tretubi. Too bad the headtube badge was altered.

The seat tube measures 56cm center to center. I've stripped the paint off, exposing the 'Columbus' stamps on the three main tubes (Charlie previously called this a 'Columbus' Tretubi bike). I had the alignment checked by a local classic bike aficionado and mechanic - he did the 'string' test among other arcane things and judged the frame to be true. He also said that the quality of the workmanship is typical for the vintage. There appears to be no crash damage and all the joints look sound. The chrome on the head lugs is shot, and the chrome on the stays is in fair condition. Other than that, there appears to be nothing wrong with this frame. It come with a Tange fork and headset, also in excellent condition except for the chrome. Here is a link to an album of pics:
