I have this one picture of a very high-end, Nervex-lug 1961 model Geminiani on my workstand being prepared for a (second owner) local rider's trip to eroica.
The GT rear derailer (original was Gran Sport) is being tested here with a 14-30t U-6 freewheel after a spring tension modification.
Note Campagnolo dropouts and very early Record front mech. Original(?) Brooks saddle was stamped 61 and the bike originally had 1st-gen Record cranks that were replaced in the late 70's to allow lower gearing.
