Well doesn’t look to fit neatly into any single category of model but not the first time we’ve seen this from Italian builders in the 70’s and 80’s. If it were mine, I think I’d call it a Superissimo because of the chrome lugs. If it had crimped top tube, you could maybe consider Nuovo Mexico. Maybe call it a Nuovo Super? Any any rate, very cool bike and will clean up nicely.
