This rifle has a derringer style patch box, original flintlock and nice incised carving on the left side of the butt under the cheek rest, the lower ram rod pipe, barrel tang and around the lock plates. It is stocked in walnut and has a wider butt ( 2 inch ) than the later type of the 1800’s. The barrel is 47 inches long, octagon to round and is signed on the top flat of the barrel ” M. Jacob ” . I believe this is Mark Jacob as listed in Kaufman’s book on the Pennsylvania Kentucky Rifle. It has suffered a break at the wrist and has been neatly repaired with pins in the period of use.
