Hello Mr. Gyrba
As a long time collector of CMPs and CMP information may I humbly say that in coming to MLU Forum have probably come to the largest collective source of CMP information available anywhere.
As to your questions concerning drawing etc I expect that you will soon be hearing from many sources.
Actual specific vehicle information other than unit markings found on the vehicle is exceedingly rare. Given a March 1945 build date it is highly probable that your particular CMP never left Canada, in fact it may never have even been issued to a military unit. Never the less that doesn't detract from its historical interest. From the pictures it appears to be in relative good condition. As you explore MLU and the websites that varrious members of our Forum have you will see that many CMPs that have been restored started the process in far worse condition.
In your search for information about this truck or similar trucks you might want to put out a call to your local community to look through old family photos, this link will take you to a series of photos that I found that where taken in British Columbia during the war, which came from somebodys family photos.
