I think the wrench would roughly fit a ⅝" (or maybe 11/16") and ¾". But the larger sized end measurements at the base of the flats is 0.71" and at the top of the flats is 0.776". The smaller end is 0.67" at the base and 0.753". It was made by Moore Drop Forging Co out of Springfield, MA.

Ford was famous for minimizing the number of different sizes of the bolts on his products. Ninety-nine percent of the bolts on the 9N tractor and plow were either 11/16" or 1 1/16" and the tractor came with a wrench with those two sizes on it.
There was a good chance that when you bought a Model T or a Fordson tractor, you got that pictured wrench with it.
