Accounts differ as to the actual number of guns completed, but there appears to have been twelve. There were three versions of this weapon; the original prototype for proof and experimental testing; three guns built to the naval pattern and intended for the "H" battleships; and eight finished to a modified design for coastal artillery use and also known as Adolph. The coast artillery version had a similar construction to the naval version but with a larger chamber. The naval guns were completed as one left hand and two right hand. Only one of these had power ramming.
