Nambe 570 Round Bowl Patented Metal Vintage

Brand: Nambe Metal: Nambe Alloy (patented) Style: 570 - The Nambe name and 5 are double struck. I was uncertain about the first number. I researched online and 5 is consistent with the one I found online., Item: Round serving bowl Vintage - Very good condition. Some scratching consistent with age & use. I cleaned with Nambe cleaning polish.
