thanks for the replies, lustrousstone I have added a picture of the base as I can not find any images of ravenhead whitefire that has this base detail . also the ravenhead glass seems to have a lot of vertical lines in the design not the broken ice type design on this bowl.
I take the point that its not whitefriars,maybe Scandinavian?
john, I will see how much money Santa brings to me .see you at knebwoth.
