Russian/Soviet M-49

The Russian/Soviet M-49 was the mask included with the Гражданский Противогаз 4 Улучшен (ГП-4у) kit.  It was made of green rubber, with a hose attached directly to the mask, and an exhale valve below.  This example was made in Yaroslavl in 1963.

Гражданский Противогаз = "Civilian Gas Mask"

Улучшен = "Improved"
