Larry Daniel & Riley Gunter's "Confederate Cannon Foundries" lists 11 known and suspected surviving Bellona heavy pieces ranging from 8 to 10". (Hazlett says 13.) These are from wartime production which is estimated at 135 heavy guns for the CSA. In 1862 they produced about 37, and in 1863 sixteen (due to a fire and an iron shortage.)

Bellona had produced about half of a heavy arty order for the U.S. before the start of the war, and these were confiscated by Virginia. Two are known to survive.

Bellona had an order for U.S. field arty but apparently did not fill it. (No known survivors.)
