Polish Maska Przeciwgazowa MP-4M

The Polish Maska Przeciwgazowa MP-4M was one of the many licensed copies of the U.S. ABC-M17 Field Protective Gas Mask. The updated version of the Polish MP-4 featured an improved speech diaphragm and a slightly different color. This example was made in 1987.
Maska Przeciwgazowa = "Gas Mask"
