Imperial Russian Zelynsky- Kummant gas mask

Imperial Russian Zelynsky- Kummant gas mask. Moscow model. Very nice and slightly worn example. Has all factory markings, paper tags on it and instructions how to use, also the paper instruction inside the rubber mask is the same as on the filter.  Maker marked "КАРТ.ФАБР. В.У.И.М" , and on the closure " ЦВПК КФ" which means: " Центральный Военно-промышленный комитет" (Central Military-industrial committee). Same name is written on the paper tags.  The rubber mask is in mint, never used condition, it has maker's mark -  made by factory "Triangle", which is written on the triangle marking - "Треугольникъ-Петроград". The mask is soft and pliable. Just one very minor damage on it. The strap is also damaged, but all parts are still present. One of the best Zelynsky gas mask we ever seen.
