PMN AP MINE (Historical Prop)

PMN-1 Mine Design Originates from Late 1950s The PMN-1 mine's design dates back to the late 1950s. It stands out for containing an unusually large amount of explosive filling compared to other anti-personnel landmines. Typically, most anti-personnel blast mines contain around 50 grams of high explosive, which usually damages all or part of a victim's foot. In stark contrast, a PMN-1 contains 249 grams of explosive that can easily destroy a victim's entire leg and inflict severe injuries on the adjacent limb. Most victims who step on an anti-personnel mine have a very high probability of survival, though they inevitably suffer permanent disability regarding their gait. However, the large amount of explosive inside a PMN-1 mine significantly increases the risk of fatalities and, assuming that they survive, inflicts much more severe disabilities. These mines are palm-sized and cylindrical in shape. The PMN-1 has a bakelite case (brown or black in colour) with a black rubber pressure-plate and contains TNT explosive. Arming the PMN-1 Mine The PMN-1 mine is armed by removing a steel ring-pull at the end of the horizontal fuze. When properly positioned, the pin on the end of the ring-pull holds a spring-loaded striker back from the stab-detonator. Removing the ring-pull starts an arming delay that comprises a thin steel wire (held under tension by the spring-loaded striker) which must cut through a small strip of lead before it is freed. The process of cutting through the lead strip takes between 2 and 12 minutes, depending on ambient temperature. After the wire has completely cut through the lead strip, the spring-loaded striker is freed and slides forward a few millimeters before stopping, blocked by the sliding gate of the pressure plate mechanism. At this point, the mine is fully armed - the only thing holding back the spring-loaded striker from the stab-detonator is a weak creep-spring on the pressure plate mechanism. Subsequently, any downward pressure on the pressure plate (i.e., when someone steps on the mine) overcomes the upward pressure of the creep-spring and pushes down the sliding gate that holds back the spring-loaded striker. This action frees the striker, which flips forward into the stab detonator, firing both it and the adjacent tetryl booster that triggers detonation of the main TNT explosive filling.
