I know Cheviot has one similar.

Check out www.cheviotproducts.com.
They have a few cast iron claw foot tubs as well as the stand alone faucets.

i think Restoration Hardware also has one similar with a deck mounted tub filler.

This is a pretty typical "double ended" clawfoot tub with a deck mounted "british telephone" faucet. We offer this same style of tub in a few different sizes. http://www.classicclawfoottubs.com/
