My apologies for not posting this directly to the list before, but I have a Campy Gran Sport derailleur set with shift levers on ebay; search under my seller name "feldmanbike." I don't want to dive into the "rating game," but all parts are in good working order and at least fair cosmetic shape and the shifters have slotted screws instead of wing nuts and the "open C" logo.
Cheers
