Vintage 70's brushed steel cylindrical lamp

Vintage 70's brushed metal cylindrical tube lamp. Large table lamp consisting of a cylindrical barrel of brushed chrome metal (steel or brushed aluminum?) or polished metal. Nice patina. The lampshade is not original: and is of no interest (plastic) except that of being in harmony. Modernist style, in the spirit of Hans Jakobson. Status: good general condition. A small discreet push at the top of the cylinder, recent socket adapted on the old, Legrand fabric cable, center of the cut-out lampshade. (relative blind stability) Size: Height (cm): 49. Width (cm): 7, 12 (bottom), lampshade (diam 31 X h23) Weight: 1, 923g.
