I did not clean the shade at all, as found, looks like very old dirt on the interior, good and dark, see pics. The top brass ring in the shade is ID 3" OD 3 1/2", made well and placed into the shade well. The base has full modern replacement wiring and plug end, all there when I found it, inspected and in working order. I did replace 2 of the 3 socket insulators due to degradation. The base was gently wiped to remove any dust accumulation.
As mentioned, I did not clean or wipe the shade. The base only is 23" tall, with cap and finial 25 1/4", large lamp. This item is in the category "Collectibles\Lamps, Lighting\Lamps". The seller is "koolfinds716" and is located in this country: US.This item can be shipped to United States.
