The front bow of the trigger guard looks like a Tc hawken, but the back is different. And just bacause it has bettle or worm holes doesn't mean it is the original stock. It may be, or it could be an old restock. I have seen a few guns that had old patina stocks that didn't have the same lines as the "known " orginals by the same builder. For instance a straight butt stock with a barrel signed by a smith that only made guns with roman nose butts. in one case, the curator had a test done. Carbon 14 dating showed the gun stock wood dated from forty years after the smith died. So while the barrel may have been made for a gun in the 1770's, the stock came from a maple that was cut in the 1830's. It was indeed an old restock.
