I briefly had two Masis, one from California, one from Verona. Both are from 1974, although that is more of a guess on the Italian. Bob Hovey thought that was a reasonable date. I took some detail pictures to document the differences, and posted them on Wool Jersey. Overall the workmanship on the California bike is better, the lugs are thinner, the shapes a bit more refined. Both ride very nicely,

I did not take decal shots since the Italian has been repainted. More pictures of the California bike can be seen in one of my other Wool Jersey albums.
