Vintage art nouveau 3 arm solid brass electric wall sconce with crystal prisms

This elegant heavy solid brass sconce is probably from @ 1950's. It can be wired in. The back has 3 separate wires for each arm. I tested them and all are working. The wiring appears to be newer. It has 10 crystal prisms. Each arms has 2 large tear drop shape crystals, 2 large in the center, 2 small ones at the top. Scalloped edge drip trays. Shell design on the top and bottom with ornate scroll design around the outer edges. It has beige socket covers. They may be replacements. It measures 15 1/4" high. 9 1/2" across X 6 3/4" D. The crystals are all in very good condition. I see no chips or cracks but there may be some light scratches. They will be removed for shipping so some assembly is required. The brass has tarnish or as I like to call it, nice aged patina. There is some scratching around the hole where the assembly plate is attached. I think it may have has a larger cover at one time that left the circular marks. I comes with the plate and brass ball that covers the hole.
