Description: The Mine G.S. Mk III has three principal components: the loaded mine body, the mine cover, and the fuze. The mine cover fits loosely over the top of the body when the mine is laid, and is raised sligktly at the center to form seating for the top of the fuze. For transit purposes the cover fits over the bottom of the mine and is secured with adhesive tape. |
|
The loaded mine body is cylindrical in shape and is closed at the top with a lid solde-red in place. After filling, the bottom of the mine body is closed with a base plate, which is pressed in and coated with cement for moisture-proofing. A central well in the mine body is provided for the insertion of the fuze. Immediately below the fuze well is loacted a C.E. booster pellet surrounding the Detonator No. 27, and below that is placed a solid TNT pellet. |
|
The A./T. Contact Mine Fuze No. 2 Mk I consists of a brass housing tube containing a spring-loaded striker retained by a shear wire. A brass detonator holder is burred into the lower portion of the housing tube. This holder contains a 1.7-grain percussion cap, below which is located a fire channel leading to the Detonator No. 27. The detonator is crimped over the outside of the holder. |
|
The mine is fired when the weight of a vehicle forces the over against the striker, shearing the shear wire, and allowing the striker to be forced by its spring against the percussion cap, thus initiating the explosive train. |
|
Use: This mine is used as a defense against armored cars and other vehicles. The mine will break the tracks of light and medium tanks, and disable other vehicles. |
|
Assembly and Arming: Place the mine in the ground and insert the fuze in the fuze well. Withdraw the safety pin from the fuze, and place the cover of the mine over the fuze. |
|
Neutralization: Reverse the arming procedure outlined above. |
|
Remark: If the mine is to be re-used, inspect the fuze to see that the shear wire is intact and in position. |
