Hy Mick 1975, welcome, it looks like you have the equivalent of a 1 1/2ton Canadian truck there, from your pictures I think the cap in the middle of the front hub is the screw in type with eight sides on it pictures are too far away to be sure. Your truck could be anywhere between a 1939 and a 1947. Post some more closer pictures and a picture of the cab interior/ dashboard, hope that helps.
