I just listed a bunch of stuff on Ebay, all starting at $1, mostly Campagnolo chainrings and derailleurs from pre-1983. I will offer shipping discounts to CR list members. My username is 'fletchermbike'. I think this URL will get you there:
All this stuff came from Ebay. I'm releasing it back into the stream. Proceeds will fund more silly bike stuff.
