OK...so I emailed the guy I bought it from and he responded that he believed the cassette to be Record as it came off a bike he parted out that had record for for everything else. When I explained to him that Campy did not make an ultra-drive record cassette that was all steel he agreed that it must be Chorus. He mentioned that I could send it back to him and I countered with a request for a partial refund of $25. He agreed and is sending me a check.

So here is what I have learned about Campy's 10 speed cassettes:

1. This forum is great place to get info.
2. Record Ultra-drive cassettes were not made in an all steel version, they came as either all titanium or a mix of Ti and steel.
3. Record and Chorus cassettes with a 12T small cog have 3 carriers with 2 cogs mounted to each, and 4 loose cogs.
4. Record and Chorus cassettes with an 11T small cog have 2 carriers with 2 cogs mounted to each, and 6 loose cogs.
5. Centaur and Veloce cassettes may have 1 carrier with the two largest cogs mounted to it and the rest loose, or else they are all loose.
