No, I hadn't, so thanks for the tip.
Having Googled, it seems a possibility, but;
1) I can't see a similar shape (yet)
2) The style of painting on Bristol, although varied, doesn't seem a 100% match.
3) I can see a few similar colours of glass in their work.
4) The form does seem (more) similar to Belgian factories (although it's not unique enough for identification)
It's certainly worth doing a trawl for Bristol and seeing if I can find a better match.
Will post if I find it.
