Here's my little orphan odds and ends pile. None of the three (3) 1/2-inch hex drive plugs on the right there are branded, and I don't know if any of them are an exact match for early SK production. In fact, my hunch is probably Duro/Indestro or Hinsdale on these, because the blade on the screwdriver bit end is more pronounced than it is on SK. (If it didn't come up before upthread, SK wasn't the only mfgr making early 1/2-in hex drive tools in this kit style). But if you want one of them, just PM me. I'm going to assume you have better options for turning sockets, but if your goal is to put the kit back to work, I'm pretty sure they are interchangeable, and one of these will function in your ratchet. If your goal is to complete and re-condition your grandfather's set - a worthy project regardless of how common these kits are, it will definitely pass the eyeball test. Nobody but you will know the difference.
