On reflection perhaps Fiscal Year or Contract Year is more appropriate than Model Year. However Model Year is what GM of Canada first used in 1935 as a prefix to the Model Number, and so that's what it was meant to show. What I have not considered is of course body style changes that were effected during each Calendar Year, and surely some Model Year trucks must have had bodies of different styles depending on when they were actually assembled and then made available for bodying? Then again with hundreds of trucks stored and then delivered out-of-phase to the sequential production number, later bodies must have been placed on trucks that in theory were "older" than otherwise identical chassis. We know that engines were assembled in chassis with no respect for sequencing, and apart from the fact that this was a consequence of pulling the first units to hand out of storage, the lack of an identifiable sequence must have had security advantages if any vehicles fell into enemy hands. To that I would add that when it came to it, engines with prefixes indicating a particular intended chassis end-user were installed in a different chassis because of .... shortages? human error?? shipping delays and losses???
