hi - trouble with these things is that whilst there has been considerable variation over the years, most countries have made similar shapes and patterns. Assume you have the same matching No. on the stopper ?? - if not then you may have a replacement.
But IMHO I'd rule out this one being made in the U.K. - that figure one is so very continental in style - and wheel engraving is not so common either.
I think it would be a rash person who would commit themselves to naming a specific country of origin, though I'm not against suggesting Denmark or one of the Scandinavian countries, despite you scepticism

................ let's see what others think.
Nice bottle by the way. Which of pix one or two is correct for proportions - picture two makes this looked a tad stretched/thin.?
