Description
This shell consists of an HE Shell Body, Mk II, modified by drilling and tapping the base of the shell. A nose plug is threaded into the forward end of the shell and is centrally drilled to allow smoke emission. The drilled hole is closed by a thin metal disc and a cotton cambric disc. Upper and lower perforated tubes surrounded by primed cambric are separated from the nose plug by two millboard washers. The smoke filling is loaded around these tubes in two increments. Beneath the lower perforated tube is located a metal container filled with 7 grains of G.20 gunpowder.
The after end of the shell is closed by a threaded thermal septum of accurately machined thickness, in the center of which are pressed 2 1/2 grains of LDNR. The shell is painted light green overall, with two 1/2 inch red bands painted around the body. Heat from the rocket motor initiates the LDNR, firing the gunpowder charge and primed cambric, which initiates the smoke composition. The gunpowder explosion also blows the discs out of the nose plug of the shell.
