PS. I'm thinking that the B&W forum picture is actually a modern photo taken at one of the Popham airfield 'Megameets'? I've seen the bike there a couple of times, on loan from Beaulieu. Ron
It is a scan from a photograph from the Bruce Main Smith collection (kept at the VMCC Library). Don't know when / where it was taken, but I assume we're talking of the 1970's or 1980's here...
