As I mentioned in an other thread, I've found a 1956 Crescent racer with the famous Simplex Juy 543. After cleaning the bike all through (and discovering that the Fauber crank and crankbox, the pedals (with a "W" on the dust cap??) and the FB Brevete low flange hubs were all as technically sound as was the shifter) I've build the bike back up again. Except that I never installed that "second cable" on the shifter. I simply can't figure out how it's supposed to be set up and work. Is there a description or instruction or manual somewhere on the www, or could one of you fountains of knowledge enlighten me?
