Our father was Mitch Gornik, the inventor of the origiinal metal Fin-Kwik. He was a tool and die maker who came up with the idea in response to my brother Mark's complaints about how hard it was to put fins on accurately. He made the original dies and had them stamped at a buddy's shop; my brothers and I did the threading and final packaging. Dad was proud of his invention and it was a real kick in the pants when Estes stopped buying from him and went to their plastic version. Anyway, I have about 20 FIN-KWIKS in their original packaging. If there is any interest please let me know. Happy rocketing. rgornik
