Ace brand was the house brand for Ace Hardware stores. I worked in a local Ace Hardware in the late 1970's and all of the drivers shown in this thread are the same as those the store stocked and sold during those years. Likewise during those years True Value had a line of Master Mechanic and True Test tools as well.
I also suspect that during that time Western Forge probably made many drivers for many brands of which Ace probably was one, other likely brands would include Master Mechanic, SK, Craftsman and probably a good number of other brands as well!
I should add, the store I worked in was decades old by 1970's and mant tool from prior years were still in stock, so the driver's I saw in the late 70's may have been there from 20 years prior.
