My purpose for initiating this thread is to create the artwork that will be printed out for a 1/35 scale jeep I've planned to build as operated by Crerar in Normandy. As can be seen, there are two different War Department/Census Numbers.
The diagram that was linked by Eric, appeared as appendix "C" section of the 4th Cdn Armd Div. around February 1943. I've no doubt of it's authenticity, but for me, I'm seeing something different in the 1944 photos.
The formation marking actually scales down quite nicely, just need to trim off a bit of the sides if wanting to conform to the 7 x 5.5 inches. I think I understand though, why the rounding down to 7 inches, as the scaling of the width results in quite a bizarre fraction.
The unit sign is much more problematic when going by the diagram measurements, as it would have you fit an almost square design into a horizontal format. Rereading Eric's post, I noticed he has switched the values around, 7 inches being the height for the AoS marking. Now this is doable, but is pushing the limit of the surface area on the front windshield. Obviously the 2" white bar will have to located within the 7 inch height.
