You are looking at a 1940 Mark 4 Gas Mask Respirator. A lot of time was spent on cleaning, preserving and restoring this beautiful mask. The mask is in fantastic condition. The straps are still stretchy, new owner must be carful as they need to be adjusted carefully as they are originals. The head harness is still very flexible, which is rare in masks of this size. The lenses and lens caps are in brand new condition. The rubber is still in good condition, has slight deterioration of rubber inside the mask, please view pictures. Obviously there is no hose, or filter here. Those can be easily found and or swapped with new clean hoses/filters. If you have any other questions, please do not hesitate to ask.
