I paid a bit more then half that for my ThreeFiftySeven, also 4 inch nickel, no indication of a refinish, same stocks, standard hammer. The safe was open so I grabbed mine and compared the two. Bought it several years ago condition is in the nice shooter class.
I would consider this one a bargain too, and if in the market for one it would have been a consideration funds permitting. But I have one and I'm content with it so I don't do any searches for these.
