CYL."/"MOD." ahead of the flats. The barrels display beautifully executed wedges of floral scroll engraving extending 4 1/8 inches from either breech towards the muzzle. The blued action features masterfully executed gold inlaid game scenes on both sides with a pair of ducks in flight over a marsh on the left and two ducks at the water's edge on the right.
