I have seen several statements of when the Canadian Chevrolet Trucks with GMC engines last used the name "Maple Leaf". This fellow says that 1951 was the last year for the "Maple Leaf" name (but, then he shows a Maple Leaf 1952 model 1773. He seems to have obtained his information from Canadian GMC/Chevrolet Truck documents.

It looks like the GMC-engine-equipped 1952or53-1955 Chevrolet Advance-Design trucks did not use the Maple Leaf name?
