Contract production for whom? Aircraft? Tool kits? AA has that nice wrench example but no contract example. Hmmm. Coincidentally, the single end wrench I posted in the Bonney thread the other day is one of those wrenches, but with the Bonney name and part #.
One of the wrenches with that B in a circle logo was IDed as a Model A Ford auto wrench so that would date it ‘28 to ‘31. Looks like Ford was buying them from Moore Drop Forging and Barcalo at the same time for Model A toolsets.
