This is a very nice replica of the famous cannon that helped decide the War between the States. John A.B. Dahlgren was a cannon designer for the US Navy Ordnance Department. Two of his famous Dahlgren 11" cannons were the only armament on the USS Monitor when it fought the CSS Virginia in 1862. This replica is made with antiqued, cast metal parts mounted on wooden “plank” base. It features 6 cannon balls, 2 buckets of grape shot and 2 powder kegs. Great for Civil War enthusiasts, classrooms and dens. Non-functioning, no movable parts. 9-1/2"x 5-3/8" base. Cannon is 6-1/2" long.
