According to Hexagon's website "Hexagon of Highgate" was established in 1963 by Paul Michaels which means he then was just 18 (if the birth date given by the BRDC [19 May 1945] is correct).
Paul Michaels is the owner of Hexagon of Highgate who ran a Brabham in Formula 1 as well as Nick Faure in an ex-Ecurie Ecosse D type.
Many thanks for your contributions, Graham! (Hoping for more...)
