Vintage bridge lamp Art Deco or Victorian floor lamp cast iron

I have a vintage /antique Art Deco / Victorian fancy bridge floor lamp.
The toggle switch to turn it on has an F on it.
The pole looks like a rope design with a ball made or carved of a marble type material and cold to the touch. Electric cord runs through the pole and is interwoven on the bridge to the socket and under the base.
It does work.
The lamp shade appears to be original. Almost looks and feels like a rawhide type material with black lacing trim on the and bottom and lacing that holds the frame to the lamp. This has deteriorated but easily fixable thread looks like leather . The shade screws on the lamp.
On the base is a black stripe that runs around just below the decorated base of the pole. At the base of the arm and pole is a wooden carved piece.
