Vintage patinated aluminium and chrome desk lamp

Vintage overly patinated table lamp from the 1960s, origin unknown. This lamp is made from a tube steel bent chrome plated arm on a black lacquered steel base. The shade is chrome plated aluminum with a white lacquered inside. The lamp is in a heavily patinated condition. The shade is corroded all over, and has some light dents. The tube arm is letting go of its chrome plating and the base shows slight deterioration. The inside of the shade has a couple marks, but in a fair condition considering the rest of the lamp.
