Hi all, sorry for the delay in replying but I was trying to get some time to check out the possibles

Anita, Steven, you make me feel better about my fish feet

I suppose whilst I do buy damaged glass, this was just not what I was expecting.. you know how it is, small chips turn into great big chunks and it's disappointing. I do have the odd very old piece that isn't damaged, one in particular a Stuart vase with applied raspberries and trails etc and I guess I compare everything to that.
Steven, I had another look at the Gulliver's book and thanks for the further reference and links

Mine isn't triangular but square, I can definitely see the similarity between the Walsh fish and the other pieces though. However mine also is enamelled in madder red around the mouth of the fish, which none of them in the book are irritatingly. Anita, my instinct was English on this one, mainly because of the flat gilding/enamelling, but I will broaden my search again to look at English and Bohemian makers.
Thank you all for your suggestions and help - much appreciated.
