For your considerations is this Fabulous Pair of Antique Brass, Arts & Crafts 3-Light Wall Sconces. Very high quality, heavy gauge brass, made around 1910. All of the original pull-chain sockets and pulls are intact and working, and the candle covers are all brass tubes with an Ivory satin finish. These have a nice, old patina and are not lacquered, so they will take on an even deeper golden brown patina over time. Fully rewired, ready to install.
Mounting these is accomplished by using four brass screws in the 4 holes (2 top, and 2 bottom). We would recommend a #14 Brass Slotted Wood Screw, or similar, however, your mounting requirements may differ. These will cover just about any size box or hole in your wall.
They measure 14-1/2"W x 15"W and stand off the wall about 8-1/2"
