Hi all, I know it is a long shot but just in case anyone has available photo of following airmen who were in May 1942 with 206 Sq in Aldregrove, North Ireland?

R90447 Sgt D. A. Harborne (RCAF)
R93325 Sgt J. G. Edwardse (RCAF)
1 380 932 Sgt N. H. Wright (RAF)

I am also interested what was their trade?
