Hi all. Having had a stroke of luck, I'm now pretty certain that this chap was Sqdn/Ldr Alfred Carr (106785). He shows up a few times in the London Gazette as being in the A&SD Branch of the RAF. Intriguingly, although one of these shows him as being commissioned, from F/Sgt rank with the original service number 356120, I can find no record of an Alfred Carr with that number in AIR78/28/6. Can anyone throw any light on this chap please? Thanks, Andrew
