I was just given a Stevens, Savage Arms Corporation, Model 15A, bolt action, single-shot, 22 rifle. The barrel stamp / inscription also says it will fire 22 short, long, and long rifle ammunition.
[A Remington Model 870 12 guage pump shotgun, and a GAMO .22 calibre pellet rifle, are the first and second members of my arsenal, respectively.]
No luck so far finding an owner's manual or part diagram of the Model 15A. Previous owner never used the rifle and had gotten it from someone else.
I guess I will follow the steps on the Savage Arms website for dissassmbling and cleaning the gun before doing anything else:
