I thought I'd add my vase into the mix too, as it's identical to yours Rosie, so we know there are at least 4 in the UK! I bought it on Ebay a couple of months ago from someone based in Glossop in Derbyshire. It was sold as Bohemian and I thought (and still think) it was lovely wherever it's from, and a bargain at £4.99.
And Sue, I'd be curious to know the asking price for the one you saw in the antique centre ......
