Description. – The fuze sits in a pocket in the centre of the top of the mine; over it sits a tin cap on a rubber washer to keep moisture out of the fuze pocket. The fuze is ope-rated by a spider frame which fits over the top of the mine and is held in place by studs which fit into slotted straps on the side of the mine.

Check that the shear wire of fuze is not damaged (if it is – discard the fuze).

Put the fuze in the mine and remove the safety pin with a horizontal pull using pliers.

Place the rubber washer and tin cap over it and replace spider cover.

Remove cover without putting undue pressure on it.

Insert safety pin or nail or strong piece of wire in safety pin hole.

Remove fuze.

Note. – You may meet British Mk IV mines. They are similar to Mk V but have an overall solid cover in place of the spider frame, and no waterproof cap.

British Mk V

Description. – The mine is operated by the V-shaped indent on the pressure plate crushing the chemical igniters of the fuze.

Assembly the fuze by inserted detonator into igniter (puuting the open ends toget-her) and fasten with the rubber sleeve on the igniter.

Insert a fuze into each of the two pockets under the pressure plate, pushing the detonator end in first, and ensure that the RED paint is visible in the gap.

Close the flaps at the ends of the pockets to prevent the fuze falling out.

To disarm

Open the flaps and remove both fuzes. The igniter and detonator must be taken and sto-red separately.

Note. – There is a Mk II edtion of this mine with the following alternations:

The fuze is in one piece and is operated by a pressure pin (See sketch).

The two pockets for the fuze are inclined at an angle to allow for easier insertion.
