This document was reproduced on the late Clive Law's now-defunct ramtank.ca website. To make it more accessible, I have copied the document in the attached file and cleaned up the formatting so the list is properly aligned (which can be hard to do on websites and forums like this).
Census 4-1-0 GWG/WEC
No. 4 Sub-Depot,
1st Canadian Base Ordnance Depot,
20 October 42
CANADIAN W.D. NUMBERS
1. The following list includes all W.D. numbers allotted to Canadian Forces in England by War Office.
2. It is pointed out that the former R.C.A.S.C. series of numbers has been discontinued and that there will therefore be no future addition to this section. Further blocks of numbers may be allotted to cover increases in Canadian Vehicle strength in the future and notification of these addition will be forwarded as they occurs.
3. We would also draw to your attention the fact that the prefix "C" which indicates a Canadian W.D. Vehicle is also applied against British W.D. numbers whenever the vehicle in question is purchased by the Canadian Forces. The addition of this prefix "C" should, however, only be applied on instruction of Vehicle Census Branch.
