A picture of the whole thing would help a lot.

It looks almost (but not quite) like Makkum (Dutch)

I think your right , i just found some maker marks that look like it , Thank you so much Gargamel ! i been looking for awhile.

That's the picture I found too JrFinds (I should have posted it and saved you some time - sorry about that). I don't know anything about pottery though and wondered if it was really the same or not. What does your Tureen look like....I'm curious!

I thought I had a piece of Makkum (which is why I thought of it), but now that I hauled mine out of the cupboard I see that I have a piece of Workum instead.

Here mines , Now i just trying to date it ? some have Blue ink and this one look a little like purple like your .

Wow that's beautiful! Maybe you can contact them directly since they're still in business (Makkum Tichelaar)
