Dear Ardy, Ivo, Walt et al,
please accept my apologies for such a tardy response to you both on your comments to the vase.
I bought it at an antiques fair in Beaumaris on Anglesey whilst on a trip to Wales, thought I'd get a little glass hunting in! It was quite inexpensive.
At first I thought Barovier with the colour and style however when I saw the Frastagliato I knew I had to do more research hence arriving at initial thoughts it could be Seguso Merletto.
So once again many thanks to you both for your considered comments.
With kind regards
Andrew
