Naval spar varnish or its poly equivalent on the inside surfaces of the stock, to include under butt plate. Not sure about the outside finish, what it is and what it might readily take.
I recently finished my wooden trailer floor in 50/50 BLO/odorless mineral spirits. Man, that turned out great and very easy to apply. If you have an oil finish, that might work on the outside. Maybe on the inside, too.
