Those are for to fix the 67M and 75M Összfegyvernemi védőkészlet (joint service general-purpose personal protective equipment) leg parts. The big one on the front is for the personal decontamination kit ( SzVCs) the side pockets are for the drug injections against nerve agents ( KÉPA), iodine pills and water disinfectant tablets. The little pocket is for the anti-fog inserts and the spare membranes. The flat part is for the chemical gloves. The smaller one is for the filter(s), there is a small canvas piece that is meant to be separate the first and spare filter if it was issued. The biggest one is for the mask and weapon decontamination kit ( FVCs-M). ![]() The originally intended carrier of the 70M is the 70M bag, it is an impregnated dark olive-colored canvas bag, in small numbers "Rába" camouflage pattern bags were also made. The 70M filter is nearly identical to the one on the PMG ( EO-18k). Painted membrane covers, the purpose and origin is unknown. The mask was made in 5 sizes and used the Soviet sizing system. It also decreases the pressure on the head by the mask. The holes on the helmet part of the mask were made for ventilation of the head so the wearer wouldn't experience overheating. The 70M has a grey-colored strap at the back of the mask, its purpose being to allow a better seal, but the mask is secure on the head without its use being employed. For the left-handed soldiers left-handed masks were made but only in small numbers, for this reason left-handed PMGs were imported as well numbers but the diaphragm cover was changed. There is a flat metal circle behind the inhale valve which helps to maintain the shape of the mask. The mask takes a GOST-compliant filter to the side, in a thread unusually made from rubber, the air reaches the inside through moustache arranged Tissot tubes. ![]() Around the same time the rim of the eyepieces were also changed to smoother angled one from the older scalar one. The strip which hides the wire that is fixing the speech diaphragm on the later ones (after ~1983) was changed to plastic from canvas. There are masks with black exhalation valve covers. The doubled exhalation valve located towards the bottom of the mask, under the diaphragm. There is a speech diaphragm located under a removable cover on the front of the mask, there are more and smaller holes on the cover than on the PMG. For soldiers who had glasses, special lenses were available in theory, but in reality there were none. The eyepieces are just a bit angled to aid the use of optical equipment. ![]() It has two flat circular glass eyepieces (the glass is one layered while on the ShMG is double layered), which can fit anti-fog inserts. The 70M facepiece is made of rubber, a different injection moulding technique and rubber (DA4 rubber in "gray clour II" on the facepiece but the filter connection thread is made of styrene) was used than on the original Soviet ShMG mask.
