I've got literally 1000's of pics, taken mainly at Brands from early to mid 80's, when a family friend used to race FF2000, (Nicholas Owen, you may of heard of him in racing circles back then?!)
I remember Wendy Wools advertising hoardings at the top of Paddock Bend, if that logo is linked, I might be able to find something? Bit of a long shot, but worth a go? Also got programmes too, so there might be something there?
When I used to go to go, the Formula Ford was normally a support race to other stuff, Mini Miglia/Mini Se7en, Trucks etc...
Can't promise a quick answer with this, wife's just had another baby, so not got time to fart at the mo, as you can imagine....!
