Other Masks

In this section I'll show other masks that aren't japanese from WW2.

AFM34 Gas Mask:
The A.F.M. 34(Appareil Filtrant Marine 34)  is a rare French Navy mask that was issued with a special helmet designed specifically for use with the A.F.M. 34. The front of the face piece of the mask was made from solid painted metal, with sides composed of a canvas material similar the A.N.P. T 31. The filter canister was connected to a corrugated rubber tube that was attached to the metal face piece between the eyes. The filter canister was then suspended behind the head via a metal clip that protruded through a hole in the back of the helmet. The metal clip was attached to the mask's head harness and was not part of the helmet itself. This design was most likely intended to make it easier and less cumbersome to wear aboard ships, were close quarters and confined spaces were abundant. The A.F.M. 34 was also sold commercially, where it was designated the Appareil L.M.B..

I actually has 2 of them. My personal opinion about the metal facepiece is that it was a kind of facial prolongation of the helmet, to protect the face against any kind of shrapnel. One of the masks doesnt have harness. 

IDA-59 Rebreather and Scape Suit:
The device IDA-59 was accepted on arms in 1960. It is intended for use by crews of submarines as for realization of simple diving works as well as for rescue in emergencies. In the latter case device allows to carry out(spend) stops for decompression due to an opportunity of change of a gas mix. The device consists from tank in capacity 1 litre with a mix heliox under pressure 250 bar. And one more of tank containing oxygen, box of an absorber, respiratory bag, oxygen device of submission of gas. At rise on a surface the respiratory bag is inflated and is used as a saving waistcoat. With the help of this device the crews of submarines left from depths up to 300 meters.

It is in good conditions and complete with both bags (Rebreather's bag and Escape Suit's bag). This one was may used in the polish navy in its communist era.

Both bags. The one of the left belongs to the suit and the black one belongs to the rebreather, it has a harder material:
