Benhurd - sounds like a super find. Looks like you're going to be occupied for a bit. One thing you might be able to do to find more information out is to go to www.bikelist.org, and perform a search of the classic rendezvous section for the word "Ochsner". No doubt you'll find some chaff with the wheat, but with a little patience, you'll find considerably more than what you have now.

Also, there are online Campagnolo catalogs posted as links from www.veloretro.com. They aren't the easiest things to search through, but unless you can post some pictures here, or find a local vintage afficienado, it might be a workable way to figure it out.

Good luck with your catch. It is certainly worth 10-20 times what you paid - if not more.
