Cleaning up in the shop and came across this wrench. No numbers just a semi colon and the letter M. It's a 9/16" and 5/8" and under 6"overall length. Fordson or Model A maybe?
I'm thinking its a Manzel supplied tool for a Ford 9n or 2n tractor
The USA is also a clue.
That did not appear until around 1925 on Ford wrenches and was continued until around 1941, according to one person I talked with recently.
The Moore Forging Company, in Massachusetts, made a lot of those wrenches for Ford and every other company.
The M was normally in a circle or a diamond on their wrenches.
They also made the first Craftsman wrenches for Sears and Roebucks, about 1938.
A good catalog of all their products does evidently not exist.
I would love to see one!
I got rid of 19 these non-Model T wrenches a while back on eBay.
I can't remember if they were the longer/larger or shorter/smaller wrench.
Note the variations.
