![]() The concept which would go on to be developed further was known as the E4R3-E1R6-E1R3 - the E4R3 facepiece design took a standard Class 'B' Gray M3 Service Mask Faceblank, removed the hose stem, a 2" slot cut in the left deflector channel from the outside, and a blanking plug and canister port were re-vulcanized onto the existing faceblank, allowing for the 60mm E1R6 Canister to thread into the side of the mask and the incoming air channeled into the usual deflector tubes without entering from the bottom. The E3R4-E1R6-E1R3 (E6-3-7) Assault Mask, with Class 'B' Gray Rubber Faceblank, typical of experimental early procurement examples. These principles involved a side-mounted canister that integrated with the existing deflector channels of a standard service mask facepiece, the canister being 60mm threaded and replaceable, and the carrier being waterproof and convenient to carry. By June 23, 1943, the bulk of the experimentation was nearing a conclusion and the final pattern for the defining features of an 'assault' mask were realized. Initial MIT concepts for a lightweight "assault" mask with a side-mounted canister ranged from the creative to the bizarre. Many unique concepts came of MIT's experiments in effort to develop an American side-canister mask, but ultimately one would go on to be developed and adopted as the E6-3-7 Army Assault Gas Mask in 1943, filling the gap for a compact, lightweight mask to be used by amphibious landing teams and paratroopers alike during the upcoming Operation Overlord. Taking note of this, the CWS established a research division at the Massachusetts Institute of Technology (MIT) in 1942 to develop a mask based off this pattern while utilizing the then-standard M2, M3, and M4 Service Mask Faceblanks. ![]() V mould was used to create a much more serviceable Mk. Later, the General Service Respirator Mk. I, which took the profile of the Civilain Duty Respirator, but successfully mounted a small 60mm-threaded replaceable drum canister on the side of the facepiece. ![]() In 1941, the British had finalized what would become the Light Anti-Gas Respirator Mk. had dabbled with masks that had canisters mounted in the chin position, but did not hold them to high regard given the inconveniences noticed wearing the mask while lying prone or crawling. Most of these concepts varied from novel at best to bizarre and impractical at worst, because, at the time, it seemed inconceivable for the American Chemical Warfare Service to develop a mask whose canister was mounted directly to the side of the facepiece without causing leaks. Since the late 1920s, one of the ultimate goals of the American Chemical Warfare Service was the procurement of a specialized mask which reduced the overall weight and size to a convenient package without sacrificing protective quality. There may be some minor signs of use or marks from storage.Edgewood Arsenal (Final Assembly), Assorted Manufacturers (Hardware) Includes metal & plastic partsĬondition: Used/Excellent - Item is near unused.

You can carry this bag over your shoulder with a adjustable strap or you can remove it and integrate it onto a Bundeswehr web belt system. ![]() Storage is simple - just one main compartment with a small sub-pocket to store things like spare lenses etc. The bag is opened by pulling on and releasing a rubber strap and unfolding the top. Made with a tough cordura nylon outer, the bag has a internal rubber lining along with seal taping to keep the water out. They are designed to be both accessed quickly but also keep water tight to safeguard the integrity of the mask in the event of a chemical/biological attack. These bags are what the German Army currently use to transport their gas masks around in. ![]()
