I have just listed the following parts on ebay:
1. Campagnolo Vintage Clamp-on Shift Levers
http://ebay.com/
2 . Complete Vintage Shimano 600 Derailleur Set<http://ebay.com/<blah>
3. Vintage Campagnolo Front Derailleur/Chain Guide<http://ebay.com/<blah>
4. Vintage NOS Campagnolo Seat Binder Bolt<http://ebay.com/<blah>
The Shimano set is pre indexed and includes shiftlevers and cable stop. Great for a restoration job on a budget.
The Campy chain guide is an unusual item. Looks something like a front derailleur but its just a guide to keep the chain from falling off single chainring set ups. Very rare part take a look by clicking on the above description or if that does not work item# 180383109422 and then click view sellers other items to see the rest.
