Kriegsmarine / Late War Mouthpiece Gas Mask

Code: 10378

Possibly inspired by the need for a compact Gas Mask alternative for use in the confined spaces of a service vessel or U Boat, Kriegsmarine regulations of March 25TH 1944 introduced a new emergency gas protection breathing device which consisted of a mouthpiece that was designed to fit on any of the standard gasmask filter. The emergency gas protection breathing device was designed to be easily carried and was intended for immediate usage in the event of a surprise gas attack.
This is the first example I have ever seen other than in photographs and is in very good condition, the mouthpiece itself being in excellent condition. The filter is 1938 dated and shows minor surface rush which in no way detracts.
What appears to be the original neck strap is in place but I can find no Kriegsmarine markings, the filters of course be generic.
