Just been re-reading this thread & thought I'd add a couple of comments. Alan Burgess ran Karting magazine from his Bromley office & also started Drag Racing magazine, which John Bennet then bought & renamed Drag Racing & Hot Rod magazine. Alan was a customer of ours at John's bodyshop, Spa Engineering, where we looked after his E Type & his wife's Alfa. A regular job every year was to re-paint the front end of the Jag to get rid of the stone chips.
At the time JB was involved with kart racing hence the connection with Alan & for many years afterwards, there was a kart frame hanging on the wall of the workshop.
I used to see Derek Penfold every year when he held autojumbles in Mitcham at a leisure centre hall, where I'd have a stall each time. He gave it up when the charges started getting too high because of repairs to the floor after each event due to heavy, dirty objects being dropped on the floor!! Shame as it was a great place for an autojumble during the winter, being indoors & very local to me!
