PMK gas mask

The original PMK mounted the filter on only the left side of the mask.

Although the filters are similar to and have the same 40 mm GOST threads as the GP-5 gas mask, they are a slightly different design, having a sloping top with ridges stamped into the metal.

The system consists of a special canteen cap, which will only allow water to flow through when connected to the tube leading to the mask.

Early versions of the PMK have a trim around the lenses and over the voice diaphragm painted black.

Older versions of the PMK can be easily acquired through sites such as eBay and military surplus stores.
