http://ebay.com/<blah> Matteo has these listed and they don't look like the GS levers I have. See the double knurling on the knob? Would these be from the first year of production? What would that be? I thought it was the strange G from the open C set, but it's not. I have a better pic if someone wants to see it. Chuck?
