Agreed John...such a wide variety of makers and all producing similar pieces. Something is telling me though it isn't Whitefriars...it's the bubbles, they are just too fine and small. Do you know if WF produced these bowls with the fine, very small bubbles? Google images show a lot of the 9099 bowls but they just don't match. I think strongly for Scandinavian now and the photo suggestions from other posters do resemble strongly. Such a minefield. Thank you for your input of course.
