If nothing else it's an unusual shape - and not something i can see in my few books. It does however, look and feel a quality item, and judging by wear on the base, cud be something like 30 - 50 years old. I hesitate to say Scandinavian, so pretend I haven't. Size: 20 cms. x 14.5 cms. x 6.25 cms. heavy with a smooth unsigned - non-pontil base, and the top edges are bevelled both inside and out. Medium straw coloured. Grateful if anyone can give a clue as to factory and/or date. Many thanks Paul.
