Serbian Заштитна маска М2Ф

The Serbian Заштитна маска М2Ф was an upgraded version of the Serbian M2, which was an upgraded version of the M1, which was a copy of the U.S. Army M9/M9A1 Field Protective Gas Mask. This example was made by Милоје Закић in 1986.
Заштитна маска М2Ф = "Protective Mask M2F"
