I'll get my two cents in early to beat the rush. I fix what needs to be fixed and leave the rest alone. A "full restoration" will always be just that, with no character or history left for later owners. A good example would be a Parker pigeon gun that came to me with great barrels, a worn receiver and furniture, and the stock broken off at the wrist, with no chance of repair. Yup, a full restoration would have been the easy way out. I chose a top quality restock by Dan Rossiter with skeleton butt that matched the rest of the gun in wear. The style of stocking and forend is "Bo Whoop" including straight grip and 12" forearm with ivory inlay". No refinish of metal was done except screws. The end result was much better than anyone's full restoration. My "restoration" of classic American custom rifles would be similar, mostly addressing bad butt treatments, improper stock finish, and replacement of modern sighting.
