Industrial Design lamp – ID please

Yesterday I bought this lamp at an antiquestore.
Seller didn't know maker or age, he attributed it to 70s.

The style reminds me on earlier designs, maybe 30s or 40s.
Unusual are the functions: It has a steplessly scroller dimmer and the scroller has a sensor for turning off and on. Not a normal switch.

Everything on this lamp looks old. It has a ceramic bulb socket, a little surface rost on the steel, and the underside of the food looks old (heavy dark red metal plate).
It is a great quality lamp, not as the typical 70s lamps I have seen before.

Any ideas are welcome :)
Thank you.

Industrial lamp

Very beautiful but definitely not as old. In my opinion, comes from the 70's - maybe Italian? I do not know why you think that the products of that time were of poor quality? It's the 80's spoil the quality of products.

Looks pure 1980s to me, when industrial design became popular in domestic environments.

Some factories used ceramic bulbholders long after they were replaced with plastic elsewhere - Louis Poulsen still use them, I believe. So it's not necessarily a sure sign of age. And steel can rust, even chrome plated, very quickly if your store it somewhere damp or expose it to certain acids.

There were still some quality lighting manufacturers around in the 1980s - as long as you could afford them!
