WW2 era Japanese gas mask. My grandmother said that my grandfather brought this back with him from the war. It was sitting in her house for 60+ plus years until her death and I've had it ever since. It is intact, but it is also very crusty. I would definitely not fully open it up! The bag seems to be in a little better condition. I have no idea if this is a civilian or soldier's gas mask? Own a piece of history. Take a look. Shipping is 48 states only and all sales final. Thanks.
