Revision as of 15:21, 19 August 2019
The Hungarian 51M but also know as 50M is a licensed variant of the ShM-1. The mask was issued to the Néphadsereg (Hungarian People’s Army), Munkásőrség (Worker’s Militia), probably to Polgári védelem (Civil Defence) and to other organisations like Határőrség (Border guards) and Rendőrség (Police).
Overview
The mask is a typical helmet styled rubber soviet mask. With two circular eyepieces that can fit antifog inserts but is has also a Tissot tube system. The valves are made of metal and has a 40mm GOST thread. The valve house and the eyepiece assembly is painted black unlike on the original ShM-1 or on other licensed variants.
Filter
Main article: 50M filter
The filter (similar to the EO-12) is a big flat canister filter connected by a hose to the mask.
Kit and Bag
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.
The kit contained:
- 51M facepiece
- 50M filter with hose
- 57M bag
- antifog inserts in tin (x6)
Service
- State organisations (army, police, Worker’s Militia, etc): The mask was used with 65M and 67M Összfegyvernemi védőkészlet (joint service general purpose personal protective equipment) and with 64M Könnyű gázvédő ruha (light gas protection suit) and Gázvédő kezes-lábas (gas protection coveralls) in the chemical troops.
- Civil Defence: The mask was used to heavy decontamination with the 65M Összfegyvernemi védőkészlet (joint service general purpose personal protective equipment) because that was more suitable for civilian purposes than the 67M. The 64M Könnyű gázvédő ruha (light gas protection suit) and Gázvédő kezes-lábas (gas protection coveralls) were also used with it.
- The industry used the mask until the 1980s.
External information
The correct name is 51M not 50M, all sources an references from that era call the mask 51M. The 50M name is a post factum name created because of the later 60M and 70M masks probably it seemed logical that the mask designation is 50M and later this spreaded.
In 1966 and 1967 several unist (boxes) of masks were were handed over to North Vietnam as a gift.
