Great question Jay!
Apparently all Masi's used this "F.MASI" crown from 1976-1990s.
Please refer to Bob Hovey's detail on Masi fork crowns which states:
"The mature design of the investment cast Italian crown (with crest and shoulder slot) remai ned in use for years with little variation. Note that while Alberto's signature appears on the
fork blade (and on the top tube), the crest bears Faliero's initia l."
Photo of same crown can be viewed on Mr. Hovey's Masi site:
