LOL I forget vintage is considered the 80's now. Hate to break it to you but this is nothing special. Its similar to an old style bankers lamp, with an 80's modern feel. I also do not think its brass, perhaps plated over pot metal. Looks like a knock off of the Tensor lamp similar to this

“Memphis Style Desk Lamp Table Lamp Stepped Glass' 70s Very Rare”

Cord style and on/off switch is a bit different:

The ad says it’s Bauhaus style.

Thank you very much Jinx and sorry for delayed acknowledgment of your feedback to this post. I do not read German and could not get the English translation of the Ebay. The lamp that I have is exactly the same and as you have pointed out the dimmer switch and wiring is different. Do you know where it is made? Germany maybe?

Hi, HU … no, I’m sorry, I didn’t see any info like that. My German is very rusty, so I copied certain parts and put them in Google Translate.

If I find out more, will post! I’m intrigued, it’s such a cool lamp. :)

ETA:

It just says ”Unbranded”:

Hi Jinx, thanks again for your feedback and my apologies for delayed acknowledgment. The translation helped a great deal.
