Hi Sean
Welcome to the never ending depths of collecting militaria. Once you have one it is never enough.
Head on over to the Canuck website. At the moment Mike Derosh is redoing his site so there is 3 different web-verions online. There is a lot of info on cab badges and shoulder flashes.
They also have one of the best forums for collecting Canadian militaria (at least non vehicle). Post questions and they are usualy answered quickly. Just be prepared to have some answers simply say "buy a book."

Best of luck and welcome to this new hobby.
