"More questions about the Fiamme stem... What year is it from? I'd always thought of it as mid-early 70's due to the recessed Allen head binder"
David,
Stems with recessed bolts began ca. 1962. My 1963 Masi Special that I got from Faliero has a 3 TTT stem with a recessed allen bolt. It must have been pretty knew, because he also gave me the allen wrench for the stem. Still have both . . .
