Four films taken by OTs, shown on the following pages, are available for downloading. 

Of further interest  is a short film, also from 1966, on the British Pathé site: http://www.britishpathe.com/  Type "Henry Thornton" in the search box, revealing just two entries. Click on "Go" on the second item, then "Preview Stills". You'll see a synopsis of the clips, as well as the images themselves, describing the go-kart project at HTS supervised by Mr Moscrop, the metalwork/woodwork master. His five-year-old son, Graham, is one of the "dragsters". It's possible to download the film free of charge, at the "preview" rate of 128kb/sec; this offers a reasonable viewing quality.
