I just got my 1946 1.5 ton home today and as I was looking it over a little closer, saw the jaws on the balancer for a hand crank as well as a hole in the grill and a support bracket bolted to bumper.
My 51 Chevy sedan (with a 235)has the jaws on the balancer also, but no access hole in the grill, so I'm guessing at that point, they were just using up the balancers they had left.
I also have a crank only H Farmall tractor 4 cyl and am curious as to what it's like to crank a 6.
