1972.
That's the first year I went to the store by myself and only spent my own money. I'm not counting the years when I picked one out for a birthday or Christmas present, or when I contributed a little lawnmowing money to the purchase. That would push it back into the '50s.

P.S. - Edited to respond to "what year you all received the "magical wand" for
gun ownership~?"
That would be 1955. I liked shooting so much with my relatives that my grandparents gave me a BB rifle, wire wall rack and red metal box Daisy gun cleaning kit. I still have the kit, although the little glass bottles of bluing and oil have all but dried up.
