Correct date of birth: 28th July, 1910.
Faked date of birth not given by either source, but there are two stories:
Stewart Wilson said he discharged from the RAAF when he discovered that his intake were going to be instructors. Re-enlisted ANZAC Day, 1940.
Kirsten Alexander, his biographer and an acquaintance of mine wrote that he was judged too old for fighter pilot training and THAT was the source of his re-enlistment. She gives a call-up date of 27 May, 1940 and an arrival at initial training commencement of 10 June 1940.
