I have one too.
the big silver frame I would have set at 1973
needs a proper Campagnolo headset.
it is probably the best bike in the room.
could use a proper repaint.
then return those Campagnolo components to it....
such a hard life these great frames lead... bought for the parts...
btw, wonder where Mario Confente picked up that seat stay cap detail that he applied to ONE Masi at the Carlsbad facility?
