Unknown Campagnolo front derailleur

[multiglot]

I have a Campy clamp on front derailleur. It has been in my possession since 1990 (or before.) it was used then. It has a "three piece clamp". I have looked through the catalogs and can't find another like it. I KNOW it is not rare, or particularly valuable, but I can't find which "series" ( Chorus, Record, etc.) it belongs to. I also have no idea of the vintage, but I estimate late seventies through eighties. Any ideas? I need to know before I post it to an auction site.

That's going to be a difficult one to tie down. If it came with a corresponding rear you could check it on the Disraeli Gears site.

Looks like it was for an aero tube as its definitely not circular. Guess would be a chorus/athena for a late 80's/early 90s aero tubed bike

I'm pretty confident I have a nearly identical one on a bike. Can check later. It is for a standard seat tube, though it might be a little bent out of shape.

Clamp is circular. Not bent. Just bad photo. It is in really great shape. Just som light chain marks inside the cage.

Is there an indent at the leading edge, in front of the badge?

Yep, so-apparently intended for CPSC US market.
