This mine, the latest development of older types "S.C.G." and "hinged lid", consists of a welded sheet-metal box with a metal lid resting on two springs. The lid has two openings covered by hinged flaps corresponding to the positions of the striker assembly and the wire-tensioning screw.

At the ends of the box are charges, each consisting of eight 200-gram slabs of TNT. On the underside of the lid are welded two short lenghts of steel tube to fit into springs; two similar lengths of tube are welded on the base of the box; all four serve to locate the springs.

The explosive compartments and the foundation of the ignition mechanism are wood. In the center of the lid, a knife is located directly above the guides. Through these guides passes a tension wire, fastening the striker to a brass adjustable hook.

The striker mechanism consists of a body with a slot for the percussion cap and holder, and the striker and spring. The nut retains one end of the spring; the thread takes the nut which retains the detonator (open and toward the percussion cap), a short length of F.I.D., and a long length of D.I.D. connecting the detonator with a second charge.

A detent with a spring provides against premature firing in the event of damage to the tension wire, and, when the lid is depressed, insures normal function by pressure on the lever, which releases the detent. This additional safety device is not found on all types.

A safety pin placed on a hole in the body of the striker mechanism in position until the mine is loaded, the hinged flaps are closed, and the mine is covered with earth. The mine functions when pressure on the lid overcomes the resistance of springs, the cutting blase decends to sever the wire holding the striker, and the lid depresses the detent lever.

1. Type S.C.G. differs in that the lid has only one opening and has a small charge.

2. Type (Hinged Lid) was the earliest type, was smaller, and was made of wood.
