Antique White Porcelain Surface Mount Light Fixture

This is a great old chunky light fixture that could be mounted on either a wall or the ceiling and would be controlled by a switch.  The porcelain is in good condition with a decided vintage look.  Manufacturers did not use the highest grade of porcelain for utility purposes and there are little bumps and discoloration under the glaze.  You could soak it in bleach if you wish to brighten up the unglazed areas where the wires enter. The only issue I note is a small chip on the corner of the base part which you can see in the third photo.

Base is 1-3/4” x 5” against mounting surface
