What kind of bridge is this?

Someone is offering me this bridge in a trade, but isn't sure what it is. Anyone know?

It's the one on the left... he says that it's "heavy."

Better pics from another angle would help.

I know. This is what I've got. Part of a larger package deal, so I'll prob take it anyway, but thinking that it's a chrome version of this:
