I made a mistake and originally posted these as SS. I now believe they are chrome plated brass.
These came off of some towers I acquired and sold. The towers were 3" SS with SS welded goose neck shanks. Very nice quality.
I don't know much about them other than that. They look stainless steel except for the handle. But after talking to a LHBS, they believe a SS faucet would not have a brass lever.
The price is SHIPPED as long as I can send it via flat rate shipping envelope.
