I remember a pretty recent thread with a similar question but cant seem to find it. I found a pretty good stash of campy parts, (including a NOS nuovo record rear wheel) and this derailleur was thrown in for free as parts...

I checked velobase, which rocks, but this seems like a hybrid between 1'st and 2nd gen C-record? The chain guide is not fully enclosed but it has the engraved shield face. Any ideas? Also the schematic would be fairly helpful if anyone has it? It's missing the hanger bolt and pulleys and id like to know if there are any other small parts i should be searching for...

Also what was the consensus on brakes like the ones in the pic? Im thinking Athena? Has white barrel adjuster and nice semi enclosed spring retainer. Super nice but conveniently missing a front bolt and washer.
Thanks so much!
