 The C/79 could fire many of the same projectiles as the C/73 but may have not been able to fire some of the newer high explosive shells that the upgraded C/73-91 could fire.Like many of its contemporaries, the C/79 had a tall and narrow box trail carriage built from bolted iron plates with two wooden 12-spoke wheels.The carriages were tall because the guns were designed to sit behind a parapet with the barrel overhanging the front in the fortress artillery role or behind a trench or berm in the siege role.
