I'm trying to find out more about the service of A.G. Beattie. He was born in Glasgow in 1916 and I think enlisted in 1939 (service number 751963). He was commissioned from Flight Sergeant to Pilot Officer in the General Duties Branch on 7 December 1942, promoted to Flying Officer on 7 June 1943 and to Flight Lieutenant on 7 December 1944. He was definitely aircrew but I know nothing more about his service. Is any information available about the units he served with? Anything would be very helpful.
