lets try this again
according to the JS (approved by both MAFCA and MARC) 1997 edition ,which is the last one published and in use until the newest 2015 edition comes out
the adjustable wrench can be plain without the script or have the Ford script
there is no reference to the Ford USA marked adjustable wrench
as the MAFCA photo states at the bottom "for more information consult the RG&JS chapter 17"
the MAFCA photo is not wrong,it just is new information to show that further research has been done on this wrench and documentation was found that showed this Ford USA wrench was introduced in Nov 1931,but read the JS to see what is currently accepted
Ford USA tools were not used before November 1931
Ford USA tools were used well into the 40s ,so there are a lot of them out there
Dave Adair has done some nice articles in the Restorer showing the actual blueprints and the reference to the dates
the 2015 revised edition will reflect thousands of hours by many people researching tools,it will as correct as humanly possible
