U.S. Air Force MBU-13/P Chemical-Biological Oxygen Mask


The U.S. Air Force MBU-13/P Chemical-Biological Oxygen Mask was usually paired with the HGU-39/P helmet. It was issued with a tinted visor with velcro fasteners, and a sock to protect the visor when not in use. This example was made by Scott in 1984.
