I would stain the ramrod lighter than the stock but not leave it natural. I would guess that the originals are natural with maybe some oil rubbed on, but they have been darkened from time and use. Since most people don't even use the rifle rod, it will probably stay whatever color you make it, but it will darken pretty quickly if you actually use it some. The tip by the muzzle will also darken if you just leave it in while loading and shooting.
