It's likely from the model T era. They did use larger script back then.

If you’re speaking of the nut on the connecting rod crankshaft journal, I’ve seen them 19/32” (usually original) and 5/8” (usually replacement), and I’ve heard that there are some 21/32” but I’ve not seen one. As others have pointed out, 19/32” is close enough that 15 mm works.

Do a search of T-1917 Ford Model T wrench to see if it is the one you have. Those sizes and description would be the standard wrench include in the tool kit. T-1917 is the tool number.
21/32 would be the standard Model A connection rod nut size and would have been a standard socket or wrench in most sets for a lot of years.
