The A-17017 Spark Plug and Cylinder Head Wrench... 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.

Re: The A-17017 Spark Plug and Cylinder Head Wrench... Steve, just looked in my tool box and my wrench has the # 50 in addition to the Moore logo.

Re: The A-17017 Spark Plug and Cylinder Head Wrench... Thanks Doug!
I wonder if this number can go any higher? It would be kind of neat to know just how many "batches" were actually done and how many wrenches per batch...But I ain't going there. Pluck |
Re: The A-17017 Spark Plug and Cylinder Head Wrench... The number is not related to "batch"
It is simply the forging die number. During quality control inspection of finished wrenches, if there was a problem, it could be traced to a particular die. |
Re: The A-17017 Spark Plug and Cylinder Head Wrench... Mine has the number 73 in the circle
