MOGG/MARCELLUS, N.Y." near the rear, and the scope mounts have built in blade and groove sights. L. N. Mogg was active in the late 19th and early 20th century as a marksman and scope maker among other business interests. Advertisements and raving reviews for his scopes were found from 1900-1904. The barrel has the standard "Old Reliable" and Bridgeport address markings on top and "CAL. 40 2 1/2" on the left side near the breech. The frame has "BORCHARDT PATENT./SHARPS RIFLE CO. BRIDGEPORT CONN./U.S.A./18315/PAT. DEC. 1876." on the left side. The pistol grip stock and Schnabel tip forearm are fancy grade walnut with very attractive figure, multi-point checkering, and a checkered hard rubber buttplate embossed with a "SRCo" monogram.
