Penny's made a run at Sears in the 70's and 80's. The earlier tools branded Penncraft were made by New Britain, later ones branded JCPenney were made by S-K. Both New Britain and S-K also made Craftsman tools (though not at the same time).
That's the wrenches, sockets and the like. As for the power tools - I don't know. Is your Impact wrench air or electric?
Yes, photos are very important.
And welcome aboard.
