There doesn't seem to be much online Canadian VIN info. I did find something on
this page though. Scroll down to the first two links under section 4 of the page. Those links are to ZIP files that contain Word documents with Canadian serial number info. After wading through all the info in the documents, one will find sections on 47-51 Canadian-built Chevy/Maple Leaf and GMC trucks. I'm assuming the same info carries through '54 and probably '55 first series, except that the Maple Leaf was discontinued after '51, according to a note in the 2nd document.
It's actually pretty simple. The first digit of the serial number is the last digit of the model year. The next two digits denote the series (and make-Chevy/Maple Leaf or GMC), and the next two digits after that denote body/chassis type. The rest of the number is the build sequence number.
So, truck A would be a '47 model 1133, which is a Chevy (or Maple Leaf) 1.5-ton cab & chassis w/ 137" wheelbase, equivalent to a U.S. model 4103.
Truck B would be a '54 model 1433, or a Chevy 1-ton cab & chassis w/ 137" wheelbase, equivalent to a U.S. model 3803.
Does this seem like it would be correct?
