I savaged a slightly damaged Campagnolo NR braze-on FD (a pay it forward from miamijim) in order to straighten the tweaked FD braze-on tab on a frame. It worked! So, I'm keeping the damaged body and mounting bolt as a tool. However, before I did any damage, I removed usable parts. The only problems were a stripped pinch bolt hole and a missing bracing screw at the end of the cage. Everything else looked solid. If anyone has any use for these parts, let me know. Here's what's available:

The spring, the cage without the end bracing screw (3 hole version I think), the lower pivot arm, the bolt for the lower pivot arm, a c-clip, and the upper pivot arm (it has a stripped pinch bolt hole).
