I just bought a 1981 Marlin 336 20" barrel 30-30 with a cheap Tasco 4x32 scope. I wonder where is a good place to get an owner manual for this Marlin? I bought the gun locally for $335 and it is in good condition best I can tell since I don't know much about these rifles. The gun was very clean inside and I didn't see any heavy ware marks anywhere. I touched up the furniture with some walnut stain and it looks pretty darn good for a gun made in 1981 for sure. Barely any surface rust which I cleaned up with some gun oil and wiped down all the metal with Wilson gun grease. I applied Wilson gun oil to the action and everything moves freely yet not sloppy. I think I got an oldy but goody.
