Wow!
Thanks so much for that! I must admit I was a bit lost when you mentioned Formations/Establishments/Theatres etc, but now it's starting to make sense, along with the fact that he doesn't seem to have a Squadron number!
He was a metal worker by trade.
His trade is listed variously as ACH/MW, M/WKR CSM/WKR, CS4SM (?!)
His rank runs from AC2 in 1939 to LAC, T/lul(?), and CPL by 1947.
I know he repaired planes, never flew.
He told a tale of being posted in Malaya and being given the task of moving large quantities of 'stuff' down from a mountain, which the Japanese had put there. Later in life he met a man who job it has been to move the same 'stuff' up the said mountain in the first place!
At some point his wife received a letter from the army saying he was M.I.A., but later he turned up in England, having been in Australia! I guess this was some time around 1942, judging by his records.
