Nice rifle it was not in storage for 70 years somebody took care of this rifle. Not sure about the rear sight.The patina doesn't look right (to me) for being over 100 years old.
If it is in fact 100% original it should bring a pretty penny.
By the pictures , I am guessing it has been refinished.
You might want to take a 2nd look at the OP's gun. It isn't engraved.I would consult a Marlin expert that deals in factory engraved Marlins. It is the only way to know, some of the engraved ones sell for 15 times that of a regular catalog model, and yours may be in that class. It would not leave my ownership while I was living though.
