Lovely vase, sorry I can't help with id.
I don't think it's Siddy Langely, I don't think she used that sort of bright iridescent strapping, I don't think it's John Ditchfield - he tends to leave the base unfinished, with the pontil scar showing.
I don't think it looks like Norman Stuart-Clarke either. They're all uk glassmakers.
Waiting in anticipation for others' comments.
