US Military Chemical Biological Gas Mask. This gas mask is in used condition, but is still almost like brand new. I am not sure, but I think it might be a M40/M42.
SIZE is M/L on the side of mask and L on top of the mask. I guess Medium to Large.
Includes everything seen in the pic. Hood, mask, and used canister w/ exp. date unknown.
