I posted some pics of an Ambrosio Champion and guessed it was early 60s

They must have made that design for a long time though, no? Or did bikeshops just have a long-lasting stock of them? I have seen it on so many early 60s bikes. John Barron's '63 Bianchi Specialissima (http://www.velostuf.com/specialissima.jpg) has one, and he is the original owner. John, if you're listening, was that stem original in '63? My '61 Specialissima has one but I don't know the provenance of the stem.
Duane Kennard's '65 Specialissima has the Grand Prix Ambrosio.
