I have a bit of a puzzler. Years ago my aunt gave me her husband's medals: CVSM, War Medal, 1953 Coronation, and Canada Decoration, GVIR issue. Later I applied for his service record, and was somewhat astonished to see that he was entitled to an Efficiency Medal, back in the 1930s, when he was in an Auxiliary Squadron of the RCAF. He volunteered for the Active Force RCAF in 1939 (new number) and post-war joined the Regular RCAF (new number again). He was killed in an accident while on leave shortly before he would have retired. My aunt said she remembered a green and yellow ribbon, but knew nothing about another medal. Now as I recall, the date for the EM was 1934, which meant that his previous service with the Queen's York Rangers (Militia) must have been counted. Here's the problem - on one set of enlistment papers he shows the QYR, but on a second it is modified by "Cadets". He was born in 1908, so unless he joined the Militia aged 14, he could not have had enough service to qualify for the EM in 1934. I'm sure Cadet service wouldn't count. But his CD suggests that they counted his service from 1939 - otherwise he would have qualified for the EM when he had 12 years in, and then he would have either been working on a 10 year clasp to the EM or the CD. He would have had enough time to qualify for both medals.
