She wouldn't have been made in the UK, but that does not mean we can't be reasonably certain that she was distributed here and in the rest of Europe. NC Sundance is the overwelming version of Sundance to be found in Europe.
I own 3 regular Sundances; HK, NC and China. All have subtle differences. It's not obvious, but since I have all 3 standing next to me, it's easier to tell for me.
All the ones I saw on ebay UK, have matched the characteristics of the NC one, regardless of the fact the seller has mentioned the country (or lack of country).
My China one came from an auction site (not ebay), the seller got it from a car boot, so she didnt know it's origin. My HK one came from a seller in the USA.
