Smith to win the DuPont Worlds Pigeon Shooting Championship in 1895 and the E.C. Inanimate Target Championship Cup in 1896, orders flooded Hunter Arms for the Fred Gilbert Specifications: drop at comb of 1 3/8 inches; at the heel, 2 inches; length from trigger to heel, 14 1/4 inches; trigger to toe 14 1/2 inches; and trigger to center of butt 14 inches; with a full pistol grip and 30-inch full choke barrels.
