This set sold at an auction in LA. They listed it as "contemporary" but didn't mention the maker.
Here's the link: https://www.loveseat.com/i/contemporary-dinette-w-2-chrome-cane-chairs/
Came across this listing randomly on 1stDibs today. At least it confirms they are Italian. The listing says 1960's - I would have guessed later. No maker's mark.
