I think I bought this about 70 years ago when I was about 10 or 12. "Wham-o Sportsman" was stamped on one side in an oval ring around the words. Anyone have any history on the manufacturing of this vintage slingshot? It's still in decent shape although I seem to have spent time with a burning glass engraving my nickname and some other graphics on each side. Just ordered some bands for it from Gary in New Jersey. I also learned that mere ownership of a slingshot is now a possible felony in the fine state of New Jersey. What's next? Good grief!
