The ShM-41 (Russian: Шлем Маска - "Helmet Mask") was a Soviet mask intended for infantry use and was issued just before the Second World War. Similar designs were used throughout the Warsaw pact.
Mask overview Edit
The facepiece is helmet styled rubber mask. With two circular eyepieces in metal assemblies that can fit antifog inserts but also has a Tissot tubes system which is an older type, not connected to the mask. The valves' housing is made out of metal which is painted mostly olive green and has a 40mm GOST thread. The mask was made in 3 sizes.
The 'Hood Style' dates back to World War I, pioneered as the Zelinsky Kummant gas mask. The mask was choosen instead of the O-11 (similar to the O-8) because the hood layout was easyer to use than a normal strap system. Several licensed copies of the mask were used in Warsaw Pact countries during the Cold War, including the Hungarian 51M. An interesting thing to note is the resemblance to the later GP5.
The filter is a big flat canister connected by a hose to the mask.
Bag and kit Edit
The bag is made of canvas. Inside there are 3 sections and 1 little pocket. The two same-sized parts are for the filter and the mask. There are 2 strips on the inner side of the filter part to fix the hose during use. The little pocket is for the antifog inserts. The big flat part is for the hose. It has 2 straps, one around the shoulder and the other around the waist.
