Subject: [CR]campagnolo derailleurs: what do I have?

I just picked up two campagnolo derailleurs and I would like to know what I have. Anyone with information about either or both, please let me know.

Rear Derailleur: Looks like an old steel Campy Gran Sport, thin body, but Campagnolo Record is stamped on the outside plate. On the inside plate is stamped 13-36. The derailleur stop is mounted on the inside cage; it looks almost like a bowling pin, it has a four-sided nut that mounts on the inside cage and from there it has a round pedestal that forms a dome at the top, and the dome is the part that stops the movement of the derailleur. On the other side of the inside cage is stamped Catena 3/32. The pulley wheels have very slight serrations on the outside perimeter, but otherwise are smooth, and have bearings inside of them.

The front derailleur: it looks exactly like the derailleur I have for a 67 paramount, the armature coming down for a cable stop and otherwise looks like a NR derailleur, except that this one does not have a screw joining the two cages at the rear of the derailleur. It has a "rivet" (I don't know that's the right term or not.). You'd have to take the chain apart in order to feed it into the derailleur.

And for those metallurgically (if there such an adverb) inclined, how is it possible to determine whether something has been rechromed or not? The rear derailleur, if it hasn't been rechromed, is virtually new, except for a scuff on the outside of the hex mounting bolt.

Once I again, thank for the information, and I still don't have the chainring bolt out yet. What promises the best leverage with available tools is a suggestion from three folks: mount the hex key into a vise and find something to fit into the now-pretty-well chewed-up slots in the back. (For those who might be interested.)

Cheers.
