question Looking to identify markings on our Canadian Chevrolet C8A HUP

[Freeland]

This HUP, rescued some 12 yrs ago from French reserve depots, bears it's original paint and markings although the WD number marking is post-war. This is here where my question marks came up and I decided to find out more. I posted the same question on the Maple Leaf forum a year ago but never got an answer. Also, the RCA museum in Canada was not able to come up with anything.

I am pretty well known with the German and US military markings from the '44-'45 ETO but my knowledge is a bit lacking when it comes to British and Canadian forces. The following signs and markings are found on the vehicle (sorry for the dark pictures, I only had my phone at hand):

 

Formation Sign 4th Armoured Division

 

This Unit Sign would place this vehicle in the 15th Field Regiment RCA (towed)

 

Unknown sign to me

 

Tactical sign, HQ squadron?

 

 

I got as far as being it a HUP from the 15th Field Reg. (towed) RCA, regimental HQ (?) which was attached to the Canadian 4th Armoured Div. (Gold leaf on green) . I suspect it being a battery HQ vehicle considering the black diamond tac sign, although I do not know what the "blue part" in the diamond means. Also, the beaver sign is unknown to me. Is this a common Canadian Forces logo? Lastly, I was wondering if there is anything to say about the vehicle's WD number (CZxxxx) origins and moreove where the HUP fits in the order of battle for that era.

 

A lot of thanks!
