I was sent this copy of a Hoverspeed sales brochure from 1982 by Steven Charlesworth. It is linked here as a downloadable PDF file, though the page previews are shown below. Unfortunately the resolution of the pages is not that great (<72dpi) as they were originally published on this site as jpegs before the days of fast Internet! They are readable enough, though.
