Hi Mike, The first badge, CD2 is the officer's badge for cadet services (Cadet Instructor List), while the CD9 is the general issue kc cap badge for army cadets. It was worn by any cadet corps which did not have another approved badge. In other words the 211 Cadet Corps had an authorized cap badge and would likely be permited to continue the use, "at no expense to the public". Mazeas has confused the issue by putting two catalogue numbers in for these badges. In the 1914 book, CD 2 is actually listed as CD1, and CD 9 is the 21st Galt Collegiate Institute Cadet Corps. I have no idea why he used CD 2 and CD 9 as catalogue numbers in the second book. (Further note, he lists the Royal Canadian Army Cadet titles as embroidered and canvas. There is no canvas title for the cadets, and any found should be treated as fantasy pieces.)
Army cadet corps organizations exploded in number during the war. They were organized in most high schools, and were issued uniforms and participated in basic military training, like drill, shooting, and other basic military skills. Most of these cadet corps were not associated with existing cadet corps or militia units, and most did not have the resources to acquire insignia at their expense. The government, supporting the cadet organizations, supplied the uniforms and insignia at public expense. Mazeas likely inlcuded these badges as they were the commonly encountered cadet badges from the 1940's.
