I recall a Campy NR front that had pivot pins that had loosened up, but could not be pulled out. It was one of the earlier ones that did not have the bulge reinforcement in the casting. It seemed to me that the steel post must have a swaged end and the aluminum was cast around it.
Steve Barner, maybe I'll cut up an old derailleur to check it out, in Bolton, Vermont
