Hello, this item is an early American flintlock musket or long rifle, likely dating to the late 18th century. The 40-inch barrel and full-length walnut stock are consistent with rifles produced in Pennsylvania or Virginia during the Revolutionary and Federal periods. The decorative inlay on the stock and the gunsmith’s name “Adams” indicate that this was a custom or semi-custom build, not a mass military contract piece. The lock mechanism, from what is visible, appears well preserved and detailed, suggesting skilled craftsmanship and possibly a gunsmith working in a known American rifle-making region such as Lancaster or York County.

The condition appears excellent for its age, with intact woodwork and clean metal components. Provenance enhances value—especially if the “Adams” signature can be attributed to a known gunsmith from the 1700s. Similar examples have sold well at arms and Americana auctions, particularly when accompanied by strong family provenance. Given its decorative inlay, preserved structure, and known gunsmith attribution, this musket’s current fair market value is estimated between $4,000 and $6,500 USD.
