no other details unfortunately other than circumstantial & potentially flawed oral history.
probably a very close friend of my Gfathers brother who flew Beaufighters and later on Mosquitoes. He (my G/Uncle) trained at Luton pre war and then after WW2 started trained on Blenheims and other things.
so it's probably early 1940's.
G/Uncles letters came from Hullavington, Prestwich, Northern Ireland, East Fortune, amongst many other places.
I dont see any military bits & bobs on the aircraft or uniform so could be prewar, but I dont really know what Im looking at there. does it look RAF? certainly G/U Bob was in RAF (248 sqdn) in UK, then Egypt and latterly Coastal Command.
