On looking at my vase and reading the earlier forum I can see that my vase is exactly the same, with the same number of scallops, circles etc. I have sent pics to Anne who I am sure will post them when she is able. I was going to get better photos done today, as I am a tech idiot and my daughter is much better than me. She was coming round when she got called into work, as two people took a sick day today.
But overall I think the photos Anne has will show enough to answer the question or lack of answer....
In my opinion, it looks like most of the found items (celery vases and other things that might be considered parts of a possible set??) are here in the UK, making me feel they were produced and perhaps exported by a British firm in the middle of the centaury.
just a few of my thoughts... I am definitely going to look at UK makers and see if i can find anything
