The drawing is cluttered, but one can make out the position of the gun when raised into firing position ("in battery") vs. when retracted behind the parapet and ready to be swabbed out and reloaded. The curved line running between the two images of the gun in the two positions shows the path traveled by the tube during its firing cycle. The drawing also shows the pit into which counterweight falls as the gun is brought up into firing position. This counterweight was made up of a stack of lead plates, which are also clearly visible here. On the gun platform at right is a three-wheeled shell cart (one wheel in the rear). When the breech of the gun is retracted into loading position, this cart can be wheeled right up to the breech and the shell and powder load rammed into gun. The powder generally traveled on the lower level of the shell cart.
