My educated guess is that the Ambrosio Champion dates from 1953 and gets its name from "The Campionissimo" Fausto Coppi's '53 Worlds road race win at Lugano.
The Cinelli 1A came out in 1960 (Rome Olympics) with the allen stem bolt and the Ambrosio Gran-Prix with the allen stem bolt probably wasn't too far behind.
It's important to remember that the very latest stuff wasn't always available on a large scale when first introduced.
Anyone else have info?
