In most cases, assuming the gun could be examined personally, it is usually a very simple process to determine if stock wood is original and if it may have undergone some sort of restoration (admittedly there are a very few aritisans out there who can make that task quite difficult); but it is not uncommon for original high-grade Smith wood to have a "shiney" or semi-gloss type appearance to the stock finish. Smith guns, even high-grade examples, remaining in "mint" unmolested and as shipped factory condition are extremely rare; most were purchased by shooters who enjoyed them for that purpose. Given that fact, many examples have been restored and restocked; so you are fortunate in that regard. As to original Hunter Arms high-grade stock finishes, I am unable to answer that question precisely. While researching Hunter employee Charles Jerred and his personal gun, I was told that he finished his own Deluxe Grade stocks with a concoction he called "rose oil". I don't know what composed the mixture (likely so many parts tung oil, turpentine, shellac, etc ?), but it was applied a few drops at a time; hand-rubbed till dry, then set aside for 48 hours to harden before repeating the process again. Jerred's son said his dad must have repeated this process "at least 100 times" on those stocks. Again, I can confirm little of the information that has been passed along; but I can tell you that I have seen the stocks for his gun and I would describe that finish as semi-gloss or dull-rubbed. It is certainly not too shiney, and exhibits wood color and grain in all of nature's fullness.
