Can someone identify a red plastic hammer, blow molded plastic, hollow, stamped tinker toy at the top? I was cleaning out my tool box and I still have it, my mom saved it all these years. My first hammer. It should be dated late sixties early seventies. I was just really wondering what set it may have come from, I vaguely remember a wooden car you could take apart and fix, it's possible thats what it's from. Thanks Tim
