Kinda looks like a Sheridan...either Blue Streak or Silver Streak. They were more expensive than a Benjamin. Buddy of mine had the Sheridan, I had the Benjamin. HIs was .20, mine was .22. 10 pumps was up to magnum velocity! We lived on the outskirts of town on our own acreage but back then (1960) no one really cared if you climbed their fence. We killed a shit load of cottontails, jack rabbits, lizards, road runners, quail, dove, horny toads, hawks, skunks......some loose chickens MIGHT have been saved a grisly death by skink or coyote. Thanks for bring back an almost forgotten memory for an old man!
