There's a reference in a US Army Ordnance Supply Catalog dated March 1945 to a 100-piece Blackhawk wrench set containing 1/4, 3/8, 1/2, and 3/4 drive socket pieces, DBE wrenches, DOE engrs wrenches, and tappet wrenches. The model number for the Blackhawk set is 100W. That looks like it could be a peculiar Ordnance Dept number (W for Wrench set, 100 for the number of pieces). For other tool-sets in the same catalog, however, it is actually the mfgr's model number. A midget socket set cites Bonney's V52 as the mfgr's model number, just to name one example. And Blackhawk did like to use the number of pieces in its sets in its model number schemes (e.g. 28-QD was a 28-pc Quick Disconnect set, etc)
There are no mfgr's model numbers provided for the individual pieces in the 100-piece Blackhawk set, except for the box. The model number for the box, categorized as a chest, is W. According to the description, the dimensions are 22" long x 9" high by 8" wide, and it comes with a removable tray, and a single key chain and lock.
Unlike the other Mfgrs cited for the other tools and tool-sets (e.g., Bonney, Duro-Chrome, SK, etc) in the Ordnance Supply Catalog, I have no wartime Blackhawk catalog to consult, and I don't know of anyone who has ever posted any contents from a wartime or even an immediate pre-war Blackhawk catalog.
Given the above explanation and descriptions, does anyone recognize the toolset, the box, and/or the model numbers?
I can provide the detailed piece-part specs. I thought I would start with the big picture first.
