Tgraph, it was Tony Cheshire and I think, Peter Falk. Barry Turner and his younger brother (who had a very quick Velocette) were around too. Neil Williams used to pop in quite frequently and graced us with his upside down flypast presence. I was in awe of him of course, moreso when I heard his story of a wing folding up on him mid aerobatic manoeuvre - and his solution to the problem.
I met Brian Lecomber at Brawdy many years later , when he'd established himself as an aero 'presence', and see his writings in Flyer mag - he doesn't look any different!
They were happy days for me at Denham. Most evenings we flocked in a variety of vehicles to a pub or out for a curry. Ian 'schimmel' Fenwick had a horrible Reliant 3-wheeler I recall, in which I often cadged a lift (I only had a shabby 350 Matchless then).
