Wow, that really did help. I think I have discovered what they are now but still no idea how old these ones are. I think they might be Feather Bowls from Belgium. It is only played in one cafe in the US, in Detroit, Michigan, but still played in Belgium. The description and pictures 'wooden cheese wheel' make me think I am on the right track now. Thanks for the new ideas and help. Now I need to see if I can find out how old they are!
