Others know more, I realize. However, from what I've seen, Faliero didn't ever build many frames himself. Even early on he had a shop with helpers who built frames to his design. I'm sure he looked things over every day, and helped out where necessary...but wasn't he really the front-guy? The man who ran the business, got the frames out to the teams and the riders, while others actually built them?
That said, my understanding is that whatever frame-building Faliero did do, ended by the early 1960s at the very latest (the Vintage Velos Museum on the web has a very interesting story about a 50s Masi Speciale, and the mise-en-scene of Faliero's shop in the 50s. If that story is accurate, I can believe Faliero built some frames...but how many?)...so, Curt, if that's truly a Faliero-built frame, it will likely have specific features common to those frames, like the long spear-point lugs, perhaps an oiler hole in the bb, possibly a 74mm bb shell with the brazed-on spacers, stuff like that. Geometry will probably be even slacker than the 60s Specials. Details like that would, perhaps, date it with some kind of accuracy; then you'd have a better idea if the thing might have been made by Faliero or not.
I'd like to hear from others who know more about this. Did the guy really ever build complete frames, start to finish? And if so, when?
