Vintage brass table lamp 3-way switch midcentury modern atomic perforated shades

This is an unusual and super cool midcentury modern brass table lamp which can be described as being in the Scandinavian style of Paavo Tynell or Stilnovo. There are no brand markings that I can find. Constructed from solid brass with a polished or lacquered finish. A tiered, three-arm cluster design with perforated cup shades on a weighted circular base. This brass and inner shades are in need of some TLC to restore the lamp's luster. See photos for signs of oxidation, commensurate with the age of this vintage lamp. It has a three-way lighting switch as shown in the pictures. It is 15.25 tall and has a 7.5 diameter. The cord is not very flexible and not up to current standards. It should be replaced if it is to be used for lighting. I provide quick shipping from my smoke-free home. This lamp is over five pounds before packaging.
