Only One Available. The Navy Mark I was one of the earlier masks made by the United States, not to be confused with the later optical Mark I made in WWII. Similar to the German Gummischutzmaske, the Mark I was issued in a metal canister. However, unlike the German Gummischutzmaske, the Mark I used a \u003cstrong\u003ewide rubber flapper type exhale valve that protruded from the filter inlet stem.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is an extremely scarce gas mask, the first of this experimental type we have offered. Most resources will point to the date of manufacturing being around 1917-1918, around the same time as the C.E.M. The mask was designed to take the elements of the British Small Box Respirator and the German Gummischutzmaske and make a comfortable and mobile mask during the First World War. There is very little solid information known about this model due to its scarcity.\u003c\/p\u003e\n\u003cp\u003eThe mask is actually still a bit pliable, and as someone who has handled 3 other examples of this mask, this is by far the most well-preserved example I’ve seen. Both the front of the mask and the canister are stamped \u003cstrong\u003e2\u003c\/strong\u003e, likely the size. The hardened rubber valve on the side of the filter is still intact but is very stiff. These valves are almost always missing from the mask.\u003c\/p\u003e\n\u003cp\u003eThe lid of the canister is stamped with a US Navy anchor stamp, and there’s also a name \u0026amp; address written on, likely the name of the sailor who wore it during trials.\u003c\/p\u003e\n\u003cp\u003eA scarce example to find in any condition, ready for further research and display!\u003cbr\u003e\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":42490219724869,"sku":"ONSV25SSOS270","price":695.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONSV25SSOS270__01.jpg?v=1741370920","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-wwi-experimental-navy-m1917-mark-i-gas-mask-in-canister-mouth-canister-type-rare","provider":"International Military Antiques","version":"1.0","type":"link"}
