USE:

This mine was designed and developed by the 38th Field Park Co. of the Royal Engi-neers, and is now being manufactrured by them on a large scale.

COMPONENTS:

The mine consists of two principal components: the loaded mine body, and the fuze unit.

(a) Mine Body: The mine body consists of a wooden box with a loose fitting lid. One half of the box contains a charge of Nobel's "808" explosive packed around a Guncotton primer. A standard British No. 2 Pressure Switch (See page 47) is mounted on a block of wooden in the other portion of the box. Pressure on the lid of the box forces down the pressure head of the switch and fires the charge.

(b) Fuze Unit: The fuze unit consists of a standard British No. 2 Pressure Switch mounted on a block of wood in the mine box. A No. 27 detonator is placed in the adap-ter of the switch and inserted in the C.E. or Guncotton primer around which the explo-sive is packed. Another small block of wood is placed on top of the pressure head of the switch, and the lid of the mine then rests on this block. Pressure on the pressure plats allows the striker to hit the detonator and fire the primer, which sets off the main charge of the mine.

ASSEMBLY & ARMING:

To arm this mine, lay it in the ground and then open the mine lid. Place the remo-vable pressure head in the switch and a wooden block over the pressure head. Close the lid of the mine, without placing any pressure on the lid.

NEUTRALIZATION:

To neutralize this mine, open the mine lid and remove the pressure head from the switch. Remove mine from the ground.
