218 Bee, that is a Stevens Crackshot. Bought it back in the late 70's. It comes in handy from time to time.
Nothing fancy, but an awfully useful utility gun. My Dad said that when he was a lad they used theirs every time they butchered a hog. One .22 Short in the ear did the job every time!
Glad to see that yours is still being productive. I'm a wee bit jealous as Daddy let his go back in the mid '80s...wish he hadn't done that!
