stand lamp

I got this gorgeous lamp from a retirement communities "free corner" about a month ago. It's approximately 6' tall and very heavy; I think the base is cast iron. The neck appears to be braided wire. I haven't decided where I'll put it yet as it would go well in pretty much any room as we have a 1920's-built home. I'm curious as to whether anyone can tell me about how old it might be, and if it might have a "name" (art deco, etc.). All four of the lights work, and it's cleaning up nicely with Brasso, steel wool and clean rages. Can anyone shine some light on this for me, please? thanks!
