Army gas mask "model 99". Similar in appearance to "model 95", it is fitted with a rubber nosepiece held inside the facepiece by a stud, and has a short canister only about 11cm high.
My model 99 has something interesting inside, a oral nasal cup. It is not usually see this kind of things on japanese gas masks. I think that it can be an experimental model. Any time, any oppinion will be listen. It is marked on Showa17 (1942). 6 points harness. There's all the pics about it!
