I made my way to the desert caravan Headquarters of the Air Officer Commanding 201 Group. I had a very pleasant interview with him (name entirely unknown to me after this long time) and went away, confident that I had "put up a good show". - Walter603
And here he is - perhaps it's not a total surprise that you could not recall his name, but you certainly seem to have "put up a good show"!
