Description
Black overall, "4K" marked on the nose.
The bomb is of three piece construction consisting of a concrete nose piece, sheet-steel body and wooden tail cone. The steel body fits over the after part of the nose and is held there by four screws. The nose houses a wooden spindle extension. A steel shear wire passes through the nose and spindle extension. A wooden spindle supported by a metal collar fits into the after end of the extension. The spindle extends the full length of the body and into the tail cone. The wooden tail cone is held to the after end of the body by four screws. It is drilled centrally to accommodate the spindle. A metal disk with a striker point is nailed to the after end of the spindle. A perforated steel cylinder is attached to the apex of the tail cone. This cylinder houses an ampoule containing the smoke compound. It is held in place by a base plate. A 1/8 inch steel safety pin fits through the tail cone and wooden spindle.
Construction of tail: Four steel fins are attached to the tail cone by screws and are soldered to the steel cylinder. The fins are braced by two sets of box-type struts.
