CIVIL WAR RODMAN FLRTRESS CANNON DISPLAY
This high quality cannon assembly is mounted on a turnable deck which has a stack of cannon
balls and a wood ammunition case and hoist as accessories. The cannon realistically traverses and is shown above elevated
on its revolving steel and wood platform which for simplicity, we are calling a “turnstyle”.
is a Rodman Civil War Seige or Fortress cannon model with the trunnions in the centered position. It was made by a master
machinist from cold rolled steel with removable turnstyle including a stack of accessory cannon balls, a hoist with wood block,
and a wood ammunition trunk. The miniature hoist replicates how the real cannon balls were moved. The carriage rotates on
the turnstyle a full 360 degrees and the cannon elevates up and down using a scale hand crank. There is a wood ramrod to clean
the bore and to load a charge which is NOT recommended without first having a gunsmith test fire the cannon. The carriage
slides in an out on steel tracks with a wood bumper at the fired end moving from the load to fired position. The recently
made cannon display is said to be “one-of-a-kind”.
satisfied by young ordinance Officer, Thomas Jackson Rodman’s results, the War Department in 1860, authorized the casting
of a 15-inch smooth bore Columbiad. Even at that time a gun bigger than anything the world had ever seen. The first 15-inch
gun, “The Lincoln Gun”, made under Rodman’s personal supervision at the Fort Pitt Foundry, was sent to Fortress
Monroe, Va., where it was tested in March 1861 and became a model for the many Rodman guns which followed. This model replicates
the Columbiad cannon design. The picture below shows the display’s relative size compared to a large highball glass, 3
