The Mammoth .577 Nitro Express Double Rifle by Westley Richards

Rear express sight has one standing, two folding platinum-line leaves marked for 100, 200, and 300 yards. Westley Richards patented front sight has longitudinally dovetailed silver bead with flip-up porcelain night sight, and folding hood.
