My understanding is that 'Maple Leaf' Chevrolet trucks were the export model made in Canada in the 1930's. The cab you discribe is a cab built by GMHolden onto the imported chassis. Rear body of the truck in the AWM photo would have been locally built as well.
My opinion is that if the body plate does not say 'Maple Leaf' and it has not got the 'Maple Leaf' name badges either side of the bonnet it is not a 'Maple Leaf' Chevrolet. You cannot take the AWM photo captions as Gospel in every case as they can often be misleading or plain wrong.
Below are two photos from the AWM showing in Photo 1 the "Maple Leaf" Chev 3 ton and in Photo 2 the 'Ordinary' Chev 3 ton. Both are Holden assembled and the only difference I can see is the Maple Leaf is fitted with the 18inch Military split rim wheel and the Ordinary is fitted with Civilian type rims and tyres, plus the Maple Leaf has the cut out guards to take the larger wheel/tyre combo. A lot of the later (1941) Chevs had the guards cut out right from new.
A nice and rare find as most Chev's around the place are 1941 and newer.
