Description
The PMD-57 is a wooden version of a box or "shu" mine with a two-piece case. The lower section is a rectangular wooden box housing the main TNT charge, the MUV-type fuze, and the detonator.
The lid section is hinged to the lower box at one end and is designed to close over the lower box. In the armed position, the lid rests on a striker retaining pin at the end of the fuze. When pressure is applied, the lid removes the pin, beginning the initiation process. Probing for small "shu" type mines with their low pressure thresholds is a very hazardous operation.
Painted olive drab.
