Russian WW1 Battle-damaged gasmask filter.
The imperial Russian Zelynsky-Kummant gas mask. A bit rusty, but still a good example. There are factory markings and instructions on how to use it. Also markings like "ЦВПК КФ" which means "Центральный Военно-промышленный комитет" (Central Military-industrial committee). Same name is written on the paper tags.
