I took the lamp apart and there is only a design mark "93-W" on the bottom. The heavy cast iron weight perfectly fits inside the pressed brass base cover. Except for the nuts used to assemble the looks original and except for a blank flamespreader, the burner looks like a straight B&H burner. This lamp is gorgeous lit or unlit. It has a beautiful Greek Revival style with goddesses on the handles and the urn style design.
It would add an elegant and functional lighting piece to any home.
