Campbell,
Welcome to the forum.
You have some nice looking vehicles.
For marking info a couple good places to start are:

and Michael Dorosh's site - Canadian Soldier in WW2 at:
http://www.network54.com/Forum/28173
The first site will tell you what the markings were, while the Dorosh site will indicate where they went.
Barry Beldam and Dana Neil also have some excellent reference material.
Good luck.
Stewart
