MissleMike,
Remember that Dell you bought...it's from the same seller. If you remember, that seller often lists keyboards which don't match the picture. I think you lucked out, but others I think were obviously scammed. Do not trust any pictures or information from this seller as they are often very unreliable. However, the prices are pretty good, so if you're willing to take a chance, you might get lucky.
Notice the words in this listing, "some are cleaner than others.. but all functional with all of the key caps", which I guess means there's a lot of these keyboards, perhaps not all the same model numbers, and I guess we'll be seeing more being listed in the future.
