just found attribution for this lamp

I usually can remember where I bought an item and how much I paid for it

So despite this being a small lamp (15 cm) and an unknown design, I remember paying a bit over the odds for it in Udine, Italy.

Very nice to have my suspicions confirmed that it is a special 1960s lamp design that is called Polysport from Swiss designer Charles Keller and made in St Gallen. I actually thought it was ceramic but it seems they are cast metal alloy with a Rilson coated finish
