BigCat1, I bought two sets from an electronics supply store in Springdale, AR in the '70s. They are out of business, now.
I don't know if Radio Shack would have anything suitable, as I haven't needed the tools in years, as everything is now solid state, and mostly preset.
You might do a search, if you're interested.
I have a habit of making other "stuff" out of junk I have laying around, that is long unused.
I'd be very surprised if anyone stocks these anywhere.
