Lamps such as these were popular during the 1860s. Components were supplied by various manufacturers, and assembled by lamp companies. The pressed glass font is in a "bull's eye and diamond point" type pattern with gilt decoration. Column is brass, as is the collar and stamped base edge. "Two step" marble base.
There was adapter/harp etc. for use as an electric lamp. If desired, I will include (but will suggest you do not rely on the wiring).
American, circa 1865.
Size: Approximately 12.12" high to top of collar; base approximately 4.75" x 4.675"
Condition: Excellent, with just slight gilt wear. No chips, cracks or repairs. (Glue residue on base from old felt; I can put new felt on if desired).
Note that I try to be conservative about condition descriptions, carefully noting any flaws. Of course, with antique items, there will be some signs of usage, and/or manufacturing defects. But overall, my customers have always been pleasantly surprised upon receiving their items, and of course, returns are no problem if I happen to miss anything.
