Let's stay on GPW pliers and not bet the farm on RAPD photos....if we have learned anything, it is that they are not 100% guarantee of anything.
I. for one, think that if you bet the farm on the PREWAR connection, then your GPW would have McKaig-Hatch pliers but I doubt that is a 100% guarantee either.
The finishes change for many mfgers from a nickel or chrome to a cadmium or blackened steel or an unfinished or painted appearance and even then you need to know WHEN this occured.
The Ford manuals do give names of potential suppliers, but the Gilmore reference was for a G8T 1 1/2 ton truck....did Ford use the same pliers in all the other factories and which factory produced the truck anyway?
The best I can figure is you need to add ALL these clues and from then you can take a guess....but while the Rockhampton photo may not tell you who made those pliers, it does seem to say that some mfgers did NOT make them
