Hi PetahW! I think you are 100% correct. Finally, I know when my rifle was made. Its really a thing of beauty! Perfect bluing, no scratches on wood or metal and its mechanically like new. Not bad for a 43 year old rifle! Marlin(Remington) just sent me a bullseye for free and its now put into the hole where the original one once was. Now, its going to the target range! Whoopie!!!!
