I spoke to the shop and they said they sell both then original "Made in England" ones at and Chinese copies so I told them I wanted the orginal "Made in England" version please as per the website.
They turned up today and I am please to say are indeed the pukka ones stamped "Made in England" and are quality so I am very happy. Therefore I guess when you order specify you want the "Made in England" version. Also "Made in England" sell at £7.50 which for included P+P whilst the Chinese copies at £5.00 so the price you pay should be an indicator too.
