In the Post 1953 Canadian section, you show a Cadet Instructor List Cap Badge (first issue)... after clicking on the link "Cadets Canada" one reaches a page with 4 cap badges on it:
top, Royal Canadian Army Cadets, as listed,
2nd badge (when issued) was for all Officers in the Cadet Instructor's List (which was renamed Cadet Instructor Cadré in the late 1990's);
3rd Badge is NOT an Air Cadet Cap Badge, but, rather a Cadet Instructor Cadré (Air) Cap Badge (worn by Officers whlo instruct Cadets and run the Squadrons. (There are, of course 2 missing here, the CIC Sea and CIC Land cap badges).
the 4th badge is, as listed, a French Air Cadet Cap Badge.
The 1st issue badge was promptly nicknamed "the corn flake" and most Cadet Officers tried to find ways to not wear it (especially Army types who usually wore their "Affiliated Unit" Cap Badge). Surprisingly, the boys at HQ decided to provide 3 separate badges - The Army one has crossed swords and the Navy one has an anchor. (The name Cadet Instructor's Cadré was chosen as it could be used in either of Canada's 2 official languages.)
Btw - you won't find a Sea Cadet Cap Badge as they retained that "round" sailor's Cap even after the change to the CF Green bus dirver suit .. er, uniform. (I think you just might have detected my disdain for the Green bag!)
