Anthony from Australia found this 12″ junior skatebike on eBay in the UK. Notice they call it a Minson Roller Shuttle. Also it has the curved front support tube and even has the original box.
I searched on Minson Roller Shuttle and found this new eBay UK listing
Anthony from Brisbane, Queensland, Australia contacted me in Feb 2020 about a skatebike he bought. Now just three months later he sent me details on the restoration. What a beautiful job. I especially love the labels for the Minson logo and Twisties slogan. Well done Anthony.
