I myself, can add this to the many wise comments.
Personally after "comming out of the closet" may add this.
Many fine antique furniture pieces are cleaned up, with waxes, and lite oil wipes, but never is the patina on the old screws, or metal fittings altered in any way.
So with this in mind, the wood and hardware, on a fine old rifle, or pistol, should be treated in the same way.
However, if you own it..it's yours, your choice.
