Had the privilege of chatting to Capt Brown a little while ago, after an RAF Historical Society meeting at Hendon.
We were chatting about his involvement in taking over 3rd Reich aviation technology after the War, and he happened to drop into the conversation - quite naturally - "Well, Goering told me ........".
Turns out that Winkle was a fluent German speaker as well as a TP, so was the obvious man to do the "technical debrief" with Hermann G in the cells at Nuremburg, just before he topped himself.
It really was a stunning moment, Teeters having a glass of red in the 21st Century with someone who had spoken - airman to airman - with Goering.
Definitely an "I danced with a man who danced with a girl who danced with the Prince of Wales." type story which I shall always remember.
