WWI French M2 Gas Mask with Straps

World War One French M2 Gas Mask with Straps. This gas mask remains in remarkably good condition despite the aged look on the inside. The rubber is still in a very flexible and well-preserved state and the straps have maintained a usable state as well. The black sealant visible on the inside is mostly solidified, although is still slightly sticky and may cling to the straps. There are no markings visible.
