These guns were purchased by Sir George Vernon in 1866.
Rate of Fire was about one shot every three minutes.
Recoil was controlled by letting the gun slide up a pair of inclined metal rails. It was actually brought to rest by a system of friction plates that were set against each other by a hand-brake.
The gun fired either solid or exploding shells cast in water-cooled moulds to harden their tips for the purpose of armour penetration.
