Canadian Chevrolet Maple Leaf 4x4 artillery tractors?

So David, I think we can agree that this was the KNIL Chevrolet ML Art Tractor, (though presumably without the front grill). Bart says it was produced in Australia, but that is probably half the story...
Any possible knowledge of numbers produced?

So this was the father of all CMP's....!

PS
Finally bought Bart's WW2 directory 2ndhand in the US at Amazon last thursday and received it today. Now I still need the one pre-1940....
