FYI 100 Sqn Royal Flying Corps and then Royal Air Force also use the skull & crossbones art within their squadron crest. (as no doubt numerous other air forces).
100 Sqn was formed 11th February 1917 and between the 1920s and 1939 many squadrons would display their squadron crest or art on their planes.
Badge: In front of two bones in saltire, a skull - approved by HRH King George VI in November 1937. The badge was the official version of a motif used by the Squadron on the Western Front in 1917.
