CZ numbers

[Andy Beevers]

Thanks for the replies,
I have to admit the other door is still bright orange, I haven't started on it yet.
The doors are original to the vehicle, (quite a statement to make considering I wasn't there!) from the history I have of the vehicle, condition and paint layers they all seem to match up pretty well.
The numbers are in two rows:

CZ6185910
L6185910
Then a rather large white star under the numbers,

why would there be two rows showing the same number?
I thought I had seen british vehicles with a number starting with an L, but am not sure how they are classified, The description for Canadian vehicles is as has been suggested.

From the insignia on the front panels it would appear to have been in the 3rd Canadian Infantry Division, 12th Field Regiment (SP)

I am not sure of the vehicle's original designation, it may have been a wireless or GS, the rear body was removed in the early 50's and had a recovery crane fitted, it may have been done in the late 40's, the crane was manufactured in 1938, Holmes wrecker serial number been verified, the cab is rust free and original, no repairs. The use since the war and storage after use as a recovery has kept it very well indeed, and 6-8 layers of paint!

I am finding all this information fascinating, please any little snippet, no matter how trivial it may seem, will be appreciated.
