They are marked National Home Lamp Council, No 955. The base and stem are made from a heavy brass.
The lamps weight almost 14 pounds each. I have not polished or cleaned the brass and there are smudges and areas that I assume can be cleaned up and polished. There is also an area on the one lamp where there are several small "rough" dots. I don't know if these can be polished and removed.
The switch is for a three way bulb and located on the base. The electrical cords are original and in good condition with no wearing or exposed wires. In general, they are in very good condition for the age. Comes from a smoke free home.This item is in the category "Collectibles\Lamps, Lighting\Lamps".
