This is a very nice example of one of the last types of gas mask that the United States fielded in WWII. The M1 Design had first come about in 1921 as an improvement of the M1919 gas mask, developed at the end of WWI. It then went through several improvements, with the M1A2 being introduced in 1934, and remaining the standard U.S. Gas mask into the early years of WWII. However the delicate \"bladder\" under the mask was prone to breakage, so it was replaced with the M2 and later M3 diaphragm based gas masks. These themselves went through several revisions, and this is the M3A1, the last design used as a standard issue. This example has the correct \u003cstrong\u003eU.S. \/ U\u003c\/strong\u003e marking on the forehead, indicating the \"Universal\" size of the M3A1.\u003c\/p\u003e\n\u003cp\u003eThe bag is labeled\u003cstrong\u003e MIVA1 C75-2JJ\u003c\/strong\u003e on the interior.\u003c\/p\u003e\n\u003cp\u003eThe mask is in great unissued condition, though as with any WWII Rubber product, it has degraded in areas, but overall is in great shape. The rubber of the mask is still supple, and the hose is still fully connected to both parts, with the canister still firmly secure in the bag. The bag is fantastic and is still still wrapped in its original sling. A great piece of U.S. WWII field gear, ready for further research and display.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":42679635771461,"sku":"ONSV9951","price":125.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONSV9951__01.jpg?v=1745269611","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-wwii-unissued-m3-diaphragm-gas-mask-with-m1va1-bag-1","provider":"International Military Antiques","version":"1.0","type":"link"}
