Type of explosive: Three blocks picric acid or TNT detonator of igniter inserted in center block.

Description: The mine consists of a wooden box, the lid of which is held in place against the internal flanges on the top by four stout springs (one in each corner). A wooden block is secured by two bolts to the underside of the lid and serves to operate the pull igniter by pressure exerted on the cover.

The explosive charge is in a separate container with the igniter and detonator inserted in the center block. A pull wire extends from the igniter over to the wire rod directly under the wooden block attached to the underside of the lid. To this wire rod are attached a trip wire which passes out through the cover to be secured to a tree or other suitable object and an antilifting wire attachment which passes through a hole in the base of the box and is secured to a peg. The igniter contains ignition composition and a pellet of powdered glass in red cement.

Employment: Used as an antitank or antipersonnel mine.

Operation: The mine will function by either of three methods: pressure exerted on the lid, tension exerted on the trip wire, or by lifting the mine to operate the antilifting devi-ce. In all instances the wire rod is moved which pulls the wire leading to the igniter.
