Thanks for looking. I recently purchased 2 silver bowls and would be interested to find more information on them, however, despite having books on the subject, I can’t even find which country they are from. I have a good picture of one side of the marks and wondered if anyone could point me in the right direction. I’m trying to add a photo of the other marks on the bowls. They look like the letter o with a vertical line through it and another o with an horozontal line. See what you think?
