wrench
 

i have an open end wrench that i do not know when it is from. it is 9/16 and 5/8. the thing i have not seen before is the ford script is very large, 5/8 inch. i ain't never seen one before, does anybody know what year it might be?

Re: wrench
 

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

I forgets: What size is the ForD Socket: 23/36?" Fits on bearing nut?

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.
