Hmm Paul. I've always 'known' my vase was Sowerby but it's been so long that I like to be a bit circumspect just in case

However, comparing it to the one on Pamela's site the fins appear to start further down the body of the vase whereas those on her vase start at the rim.
So whilst I was 'sure' but trying to appear not just in case, it might in fact be that either mine or hers isn't Sowerby.
I was happy with mine being Sowerby because I think they produced that blue in a boat shaped bowl so I felt ok with whatever research evidence I found at the time.
Not so sure now
