Those "32nd" sized wrenches and sockets were weird, I think they were for early Ford (A and T) and nothing else that I've ever heard of. They were included in sets for many years after those cars were gone. Maybe just to stretch the sets to seem bigger than the competition. Seems like an early wrench to be metric marked.
Yes, I recall the Ford 8N tractor having 19/32" headed bolts... possibly on the engine to bell housing. That, coincidently is almost exactly 15mm. I'm not sure of the age or manufacturer of the wrench.

I think Bridgeport Hardware "Pyramid" or "Hy-Bar" wrenches:

Catalog says "marked in inch and millimeter sizes" and you can find a bunch on eBay with both fractional and metric markings.
My dad told me that 25/32" was the size of the fastener that held the timing gear on the Model T and A.
