The 'Blue Book' Nos. stop in 1945 - and I believe this one is sometime after 1950. The point of the post, however, was to comment on the unusual format of the number. We're accustomed to seeing the No. without a 'stop' in the middle, and as I hadn't seen anything in this style before it stood out as unusual. I don't know who was responsible for making this bowl as I haven't researched the very late Nos. I assume it is British - and I believe from the early 1950's onwards the same group of Nos. incorporated ceramics, metal and glass. Am I correct, as for a while I thought this might not have been a British piece. thanks for looking.
