Early 1970s OTASCO in Fairfax OK was the scene for my first firearms purchase - a 20ga. Winchester 1400 auto shotgun. My FIL bought both of us a Marlin 336 in .30-30 at the N. MacArthur Gibson's in OKC so we could deer hunt together back in the 80s. I can't recall making a purchase at Mashburn's but certainly went in there often enough. My Ruger .22/45 was purchased at SW Shooters for my daughter and I to have shooting outings back when she was a teen.
