Just had the following reply back from Orrefors:.................
""Can you find any signature in the bottom of the vase? I cannot find any when looking at the picture. Orrefors has used signature for quite some time and so has Kosta.
It could be Orrefors but it might as well have been made somewhere else. I am sorry not being able to help you. Best regards""
It's true, of course, about the Nos. and signatures on their pieces - you only have to look in some of the books and webb sites. Unfortunately, the smallish flat base area on this one is so well worn and scratched that it's virtually impossible to detect if there was ever anything there, although I sense some vestige would have remained had it been done originally. Would be great if all Nos. and signatures were put within the concave pontil.
I will now try the V. & A. in London, so :X:
