Remarks :

Introduced into the German Army in 1916. Since the front of the bedding was shaped like a semicircle, it was able to traverse 360. As Gas shells it used the lacrimatory B-Stoff (with Xylyl bromide), and the lethal C-Stoff (with Mono or Tri-chloromethyl cloroformate) and D-Stoff (with Phosgene). Projectiles included also a special message shell designed to burst in the air over the addresses position when all other means of delivering it had failed. It could be carried either by two men with the help of poles, or, after two wheels of 75cm diameter had been stuck onto the axles of its bedding, drawn by hand (see the picture).
