Manufactured c. 1916-1918. "Crown/crown/U" proofed, "NS" marked hammer. Matching visible serial numbers on the frame, trigger assembly, hammer, breech block, and the interior of both ribbed walnut grips.

Fine, retaining much of the original finish with some light edge wear, signs of filing on the backstrap, thinning on the balance with mostly brown patina, some minor spotting, and minor handling marks. The grips are also fine as sanded and re-oiled with some light handling wear. Mechanically excellent.
