I have seen a similar pattern in objects from Marcolin, Ronneby.
Tina, I have emailed a couple of pictures to you.......
As mentioned, I have some photos of a Marcolin object with similar pattern.
I can't post the photos here as they are eBay photos, and I can't remember who
the seller was, thus I can not ask permission to post them here.
However, if someone would like to see them I'll gladly e-mail them to you!
