Rare, Bauhaus desk lamp (in style of) Hala or Daalderop, 1920/30s, The Netherlands

Beautiful, industrial style, Bauhaus desk or table lamp.
Its design looks a lot like an early desk lamp of Hala Zeist or Daalderop. From the 1920/30s.

Seen its age, the lamp is still in a good, unrestored and original, working condition.

You can turn the lamp on and off by pulling the small cord. Probably there has been some sort of decoration on its base or a switch, which is not there anymore as you now only see some small screw holes.
