We think that Jefferson Glass made these pancake french opalescent coin dot lamps in the 1930's. Previously thought they were made by Fenton, but Fenton's chimney is shaped like a pulled tulip -- not the bulbous shape seen here. 2 are available, one has a rim-chip on the bottom of its chimney, hidden when sitting its socket. Otherwise, both in excellent condition. They stand 11" tall and about 8" wide at the base. Original wiring (2-prong plug).
