20 gauge "Sportsman" age?

[BrandonSr]

First time posting and was wondering if yall could help out in trying to determine the age of this shotgun. On the left side of the gun it says The Sportsman, Remington Trade Mark, 9015 stamped below. It has 3 ducks on one side and 3 pheasants on the other. On the left side of the barrel it has Full C E, and the right it has REP, anchor. Is there anyone that can help out or tell me if I'm missing something? Thanks for any help
