Lynne — What a gem. What Richard Golding omitted to say was that it is one of the earliest examples of Okra, made either in Yorkshire or during their first few months at the then new Broadfirld House Hot Glass Studio, see here and here.

Thank you Bernard! it is a very pretty piece, not at all like the Okra of today. I can't decide which style I prefer really, they are so different. And so difficult to decide whether to sit on it, or sell it. I am trying to limit my "keeping this for the future" bits to paperweights and perfume bottles, but .....
Thank you for the links also - very interesting.
