Bill, I would use the original stains like Rich mentions. I would stain with a Q-tip or a small acid brush. Stain darker than you think you need and then take it back with steel wool or scotchbrite until you're happy with the color. If you're not sure, a little water wiped over the surface will give you a better idea of what it will look like. I'd finish it just as you did originally. If you're not happy with the stock finish/spot finish, steel wool the whole stock and apply one more coat of finish, you're basically getting rid of the grunge that has accumulated overt time on the original finish.
