Thanks for your comments. I don't think it is Chinese but I agree with Gareth that it doesn't look like Royal Crest. I bought it because I thought that the quality of workmanship was very high and it had the feel of some of the early Selkirk paperweights, although I don't think that it was Selkirk. You can't really see from the photograph but the top half, which has been made on a separate iron and then joined on before casing, is very fine and delicate. I tried making some paperweights a bit like this when I had a studio in Norfolk, (England), in the early nineties and the "fountain" at the top looks very much like the ones I was making. But it's not signed!
