My father's (now mine) winchester 12. Believe its stamped '56. Dad hated grackels (blackbirds)with passion for eating his dog food. We lived near a feedlot with a grain silo so thry came in like a plague every year.Our best year dad n I shot 800+ shotgun shells, reloaded them and shot them again. That happened almost every year for ten years. I have been hunting awhile n so I know it sounds like b.s. so take it if you like it, if not sorry. Its retired now, but that's still old trusty.
