For that finishing touch, here are a couple of Campagnolo ferrules. These fit the old school stainless housing for derailleurs. One is spindled (620) to fit the Campy "Divers Bell" stop, the other perfectly fits a Nuovo Record derailleur. Priced per pair, two pair available. There isn't any additional shipping for both pair.

I'll ship same day or next.
I use eBay's Commercial Shipping Rate, saving you money.
Please, no returns. If I make a mistake (and I have), I'll take care of it (and I have).
I'm very happy to combine shipping;
       1)Actually, this happens quite often, buy a bunch of stuff, let eBay charge shipping for each item, and I'll refund the
           difference right away.
      2) Best way, put items in your cart and request a total. On a phone, click on the 3-dot menu (upper right) to request a total.
I ship via U.S. Post Office with Ground Advantage, includes tracking.
