Here is an old (I imagine well over a century old) 3 arm brass sconce in original condition. The middle gas arm retains its original gas jet. The two outer arms have 2 old nicely etched 2 1/4” fitter shades and old brass fitters. It measures 13” across with shades fitted, 13” high and comes out from the wall 10-1/2”.

One of the electric arms appears to have been soldered as you can see in the picture.

A hole was drilled in the back plate at some point.8

The sconce needs to be rewired.

This great old wall light shows strong vintage character and if restored would have an amazing decorative presence.!
