Coincidentally 1911 was the year that Haynes in Maidstone (then Haynes Brothers) became the first Ford distributor in Kent when Bernard Haynes was taken for a demonstration ride in a Model T up Boxley Hill, a twisty, steep incline over the North Downs linking Maidstone with Chatham, and he was so impressed with it's performance and competitive price he ordered one immediately, and so started the long association with the Ford brand (

I wonder if there was any link between that and the Ben Nevis expedition?
