that rifle looks really rough on the outside and I would bet the insides are equally bad. The bore could not have faired well nor the action parts. The receiver looks better which may indicate that it is made of an alloy. I agree with Cryano that the rifle needs to be stripped to determine if it will be a shooter or a wall hanger. The rifle isn’t a Ruger nor a Marlin model 60. Winchester as well as Remington made tube fed .22s similar to this one many years ago and many were sold under ”house brands” like Sears, Montgomery Ward, and others. Perhaps the OP will clear this up after cleaning it up a bit.
