If the pores are still filled and it's just dulled a bit then all it needs is a cleaaning and a little maintenance. Remove the metal from the stock(inckluding barrel bands) and wipe the stock down with a rag(or paper towel) moistened with mineral spirits. This will clean the finish, removing hand oils and crud. Then apply a couple of drops or TruOil and rub into the wood. Use just enough oil to allow the hand to slide, but leaave no appreciable buildup. It should just make the wood shiney, no more! This can be repeated until the finish is nice and even. Allow enough time between coats for the oikl to completely harden. I can sometimes get 2 coats a day here in Missouri but sometimes only 1 if the humidity is really high.. When the finish looks done you can either leave it alone or do as Winchester did origially, lightly steel wool(0000 grade) and apply a nice carnuba type wax.. buffed by hand.. renew the wax as it wears away and the finish will last forever.
