The Hungarian 67M (also known as 65M) is a Civil Defense gas mask issued to the Polgári védelem (Civil Defence) and to civilians during the Cold War.
The facepiece is made of rubber coated green canvas. The valve housing is the same as on the 60M with a 40mm GOST thread (There are masks with different eye lenses. Those have the same as the 76M has. And there are masks with the ShM-41mu styled valve housing those can be identified from the negative bumps). It is glued and squeezed to the canvas with a metal ring which is covered with grey tape. The eyepieces are crimped on metalic copper colored steel alloy assemblies, the same as on the 34M, the only great difference is that antifog insert fixing ring was used rather than the previous c springs to allow the use of the Soviet 56mm antifog inserts. The head harness is also the same as on the 33M and 34M, 5 pointed 3 part adjustable and elasticated with 3 spring in every strap. The straps are connected on the back to a metal piece which is bolted to a leather square. A third additional strap is goes around the neck to provide airtight seal and there is a carrying strap on the back bottom as well.
Kit and bag
Originally it was issued with a hose and the 60M filter with the 57M bag (the bag of the 60M mask). This set was used by the registered and non-registered members of the Civil Defence. The 57M 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. For carrying it has an adjustable shoulder srtap and an also adjustable waist strap connecting with a carabiner to a D-ring.
Later when the 70M filter was released the mask was issued with the 70M filter and PV-75M bag (or just called 75M, the same as on the 76M) to the civilians. Simple canvas bag with 2 smaller parts in the lower section. The smaller is for the spare filter. The bag has 3 straps: one on the shoulder and two for fixing around the waist. It was made in several colours but the difference is minor.
The kit contained:
- 67M facepiece
- 60M filter with a hose or 70M filter with hydrophobic socket
- Bag (75M or 57M)
- Anti-fog inserts (x6) (or sometimes anti-fog soap)
It was used with 65M and 75M Összfegyvernemi védőkészlet (joint service general purpose personal protective equipment) and with Védőmunkaruha (protective work suit made of thick canvas, it gave minor protection against toxic agents during clean up). Important factories stored these masks alongside with other equipment (like ERBVCS) and certain workers were trained what to do in case of a war (non-registered members of the Civil Defence).
The mask was issued to the MN (Magyar Néphadsereg - Hungarian People's Army) too but it was more like storing, those were never used by the army because the MN always had enough 60M and 70M masks.
The design dates back to the 28M. In the 1960s a new cheaper mask was necessary for the Civil Defence than the 34M. To reduce costs a lot of parts from the 34M were reused but those were made of a cheaper steel alloy and not of copper as on the post war 34M masks, including the eyepieces with a little update (mentioned in the overview - to allow the use of the 56mm Soviet antifog inserts) and the buckles. The only great change was the use of the 60M valve house. It was already in production and made faster and easier the issuing and technical service of the new mask.
The masks is often confused with the later 76M because of the many similarities.
