JM stamped, so this is a good one. Manufactured by the original Marlin firearms plant, before the Marlin acquisition by Remington.
Gun is in excellent shape. Recoil pad is showing its age, which is normal - not from use, but just from time passing. This gun has not had a lot of use. I have fired probably 15 rounds through it. Has been in the safe with a dehumidifier most of its life. Bluing is excellent. Iron sights. Ready to accept rings and a scope.
