Yes, I cracked that mystery several years ago.
Androck Phillips head screwdrivers like the one Don is showing have shown up in the UK and elsewhere in the ETO and also in the US for many years and became a WWII collectors' choice, especially for Dodge 1/2 Ton 4 x 4 trucks, and later, for GMTK's, as a somewhat questionable alternative with questionable provenance for Vlchek screwdrivers of the same type. Questionable because there was no substantive information or evidence other than them showing up in surplus lots, and, as Mintgrun alluded to, the fact that the name "Androck" is found on antique and vintage kitchen utensils (spatulas, strainers, sieves, sifters, wisks, etc). Putting two and two together, I tracked it down to a brand name of the Washburn Company, which was largely converted into a defense production plant during WWII. Products included tent slips, tent pegs, and can openers, but also bomb parts (arming wires), and of course, tools, including a $53,000 contract with the US Army Ordnance Dept in late 1942 into 1943. ORD owned the tracked and wheeled vehicle maintenance role and they bought tools for that responsibility as spares for on-board toolkits that the vehicle OEM's were supplying as well as equipping rear echelon depot maintenance shops.
EDIT: They are somewhat rare. I have only found a few in the wild.
