Mortier de 150 mm T Mle 1917 Fabry
The Mortier de 150 mm T Modèle 1917 Fabry was the standard French Heavy trench mortar of World War I. It remained in service through 1940, with some 1,159 available during the Phony War. The tube was supported by two recoil-recuperators in a flask-rocker assembly that was mounted on a platform with six fixed spades. The finned mortar "bomb" was loaded from the muzzle, but the propellant was loaded from the breech and ignited by a percussion ignition system.
