weapon with a bore. All survivors are rifled, though this may have occurred long after manufacture; this was a common practice during the war. Surviving Wiard guns vary considerably in manufacturing details and markings.[ Documentation survives for orders of 45 6-pounder Wiards, six 12-pounder Wiards (though at least 13 survive), and 12 12-pounder Wiard rifled howitzers.

s without interference from the undercarriage. Wiard altered the shape of the carriage's cheeks, relocated the axle and provided a long elevating screw; this made firing at elevation of up to 35 degrees possible. It also meant that one carriage could slide beneath the next, allowing for more efficient storage and transportation. Other innovations included a flat trail plate with a metal keel (preventing the rifle digging itself in the ground upon recoil), and a better system for braking the carriage without damaging the iron tires.

s. The US Navy Ordnance Department under Rear Admiral John A. Dahlgren awarded Wiard a contract to produce two rifled guns of about the same weight as the smoothbore XV-inch (381 mm) Dahlgren shell gun. Wiard was to be paid $10,750 in 1860s money for each gun. The result was probably one of the most complex guns ever cast in one piece. The reinforce area around the breech was nine inches larger diameter than the bore and concave in profile. Running through the reinforce were numerous fluted passages for cooling, made with shallow S-curves. One gun did not survive the manufacturing process when the numerous casting cores resisted removal; the other gun burst at its first shot. It appears no further development occurred, though an artist's concept of a similar proposed weapon survives.[

1881 conversion proposals
In 1881 Wiard proposed to the Secretary of War the conversion of numerous existing Rodman and Parrott coast artillery
