1941 Jun 10. Flight Lieutenants to be Squadron Leaders (temporary). Cyril Gordon Davies
1946 Leaves UK for Melbourne with his family
1978 Died Australia My grandfather Cyril Gordon Davies . My mother has told me that he was a Wing Commander in the R.A.F. on retirement, but doesn`t know any of his other service details. Apparently my Grandfather rarely spoke of his wartime experiences, so details are hard to come by. All I know is that he was born in 1899, and served in WWI and WWII. That would have made him fairly old by the outbreak of WWII (40 yrs old).
