In looking at my information above, two things to correct. Mac MacDonald was a New Zealander (not English!)and the flags are the Union Jack and... I'll have to check the other. The other flag relates to Armstrong 'Doc' Lyon who was from Pennsylvania originally, trained in Canada, did two tours of operations, was credited by the end of the war with 3 enemy a/c destroyed, 1 shared and two damaged. He was awarded the Distinguished Flying Cross, London Gazette 16 February 1945, when he was serving on 214 Squadron (Lancasters). His first tour of operations was on 75 Squadron Stirlings. Post war he was retained in the Royal Canadian Air Force as a gunnery officer. I know that Doc Lyon came out to New Zealand to visit surviving crew members of 75 Squadron's AA-U in 1990(?) I think. All except NZ rear gunner Mac MacDonald survived the war. MacDonald was killed on a 7 squadron raid on 20 May 1944. Sadly NZer Maurice 'Des' Anderson, the original Navigator in "Alexander's Ragtime Crew", committed suicide after the war, most likely due to the effects of war. Regarding a better photo of the crest, Dave, I will see what I can do.
It was very sad about Des Anderson. The crew had survived 22 ops , the last four being "very torrid" in late September 1943. Alan Alexander recalled that on the 3rd October they had to do an early morning ASR search over the North Sea and early that same evening turned out for a raid on Kassel. Approaching Hanover , the F/E found Des out cold so they returned via Texel , dropping their bomb load on the searchlight/flak batteries. "The MO found that Des had cracked with a nervous breakdown. He never flew again."
I still reckon it's the Stars and Stripes for 'Doc' Lyon
I really am in agreement over the Stars & Stripes in the background rhs - I could not find any flag from the southern states (it was just a guess originally) that looked similar and it would need to represent Doc Lyon from the US as a whole.
pjw4118 posted a photo of Stirling BK777 AA:U with the nose art of 'Alexander's ragtime crew'. I am writing another book on the Stirling and will include many samples of such nose art. I would like a decent resolution copy of this if you can help please?
