Attended the inaugural meeting that set up the Mini Seven [ Mini 7 ] Association, along with a few Mini Racers, like Reg Cook.this would have been 1972 / 73 from memory, as had my car from mid 1971 to April 1974, when I got my first Sports car, the A-H Sprite
I was a non-racer but interested as ran an 850 Mini, in Trials Sprints and Hill Climbs - The Association was to be for all sorts of Mini activity but became a Racing Series which was hugely popular and with many well known drivers as seen by the above posts.
