The barrel, patchbox, buttplate, sideplate, eagle inlay, triggers and trigger guard are 100% Jacob Snider made circa 1842-55 in Hopewell and/or Liberty townships, Huntingdon/Bedford County, PA. This area along the Raystown Branch of the Juniata River is also known as the "Woodcock Valley".
However, the stock architecture is not typical of Jacob Snider rifles. I would need to examine the rifle closer to determine if it is original or a later re-stock.
