Vintage 1950's-1960's "Shoot-a-Top" by Lapin Products - This top launcher is really cool. You attach the elastic band to the top, wind it and push the pin in to hold it. Then pull the pin to launch it. I only wound it one turn as I didn't want to take the chance of ripping the band. I think that even if it broke, you could replace it with the right size rubber band and it would still work well. Made of plastic and is approximately 6" long.
