This igniter is used n the wooden box mine described elsewhere in this pamphlet and also in the Stockmine and Schützenmine 42 and wooden box mine U.B.1

The igniter consists of a bakelite tube about 2.5 inches long, 0.5 inch in diameter carry-ing a spring-loaded striker. The tension of the spring retains a cross shaped pin in a hole in the striker rod, firmly against the top of the bakelite case. The percussion cap is car-ried in a tube screwed into the base of the igniter. The tube is closed by a screwed cap. No safety device is fitted. The screwed cap is removed and a detonator inserted when required for use.

Pressure on the arms of the pin, or tension applied to the loop of the pin will cause it to withdrawn. The force required is reported to be between 6 and 10 lb. weight. The striker is then impelled forward on to the percussion cap by the action of the spring.
