OK...I have been inventoring all of my Model A tool items as described in Section 17, Revised 2016 of the MARC/MAFCA Restoration Guidelines and Judging Standards.

I have a few A-17017 Spark Plug and Cylinder Head Wrenches of the 9/16" hex head type (October 1928 thru production).

On the back side of these wrenches have an "M" in the center of a circle for the Moore Drop Forging Company.

Toward the 9/16" hex head end of the wrench are numbers which indicate a forging batch I guess.

These numbers range from 3-45.

My question then...were there any wrenches, that you may have in your collection, that have a number greater than 45 on these wrenches with the 9/16" hex head thickness?

NO...I do not plan to do any research on this...I just find it interesting!

My guess is that when the company went from a 3/4" to a 9/16" hex head thickness...they started the "batch" numbering all over again because I have the early one with the 3/4" hex head thickness with a 10 on it.
