Welded to the lower right side is an outlet port to which is screwed a curving outlet pipe, 278mm in length, ending in a brass release valve with actuating handle.Ī circular maker's plate of mild steel is welded to the upper centre rear of the tank. An oil filling tube with a brass screw cover is welded to the upper left side. However, the lower section of the cover hinge and the clamp strap on the opposite side still remain. A steel collar surrounds these, originally to locate the (now missing) protective cover. A brass pressurising valve, brass needle pressure gauge (both with knurled wheels) and propellant filling point are all located at the top of the tank. Three ball support feet are attached to the base.

The oil tank is made from a heavy-gauge steel tube 330mm high with domed ends welded top and bottom, and painted black overall. This is the medium version of the German 1917 model flamethrower.
