Description
The Navy Diaphragm (ND) Mark V gas mask, developed in 1957 for U.S. Navy forces afloat, used a single, plastic, monocular, visor-type eyepiece, a departure from the earlier Navy Mark-series diaphragm gas masks, and the only U.S. gas mask to use this particular monocular lens. The Mark V had an excellent field of view due to the broad lens, but it was prone to fogging. The US Navy Mark V Gas Mask is interesting in that it is the only US gas mask to use this particular setup. The design is nothing like the earlier Navy diaphragm gas masks. The two filter canisters provide improved protection, but this feature causes more inhalation resistance. That is, more effort is required to breathe under normal working conditions. Wearing the mask in extended training exercises, such as CBR/NBC recovery operations, becomes tiresome. The ND Mark V replaced its predecessor ND Mark IV during the 1960s and 1970s. The Mark V was itself replaced by the MCU-2/P gas mask, starting in 1983. In Original Carry Bag, With Filter Canister in very good condition.
