MC-1

MC-1 is a Polish most popular civil gas mask from PRL.
MC-1 were produced by MASKPOL in 2 variants Green And Gray.
They were equipped with plastic valves with a thread of 40 millimeters. The set also included the FP-5 combined filter.
The inhalation valve is directed at the visors so that the glass evaporates when you inhale, this was a common solution for masks from behind the Iron Curtain.

All MC-1 were produced in 4 sizes ([0,1,2,3] 0 is smallest 3 is biggest)

This one is from the year 1985, and it was the first gas mask in my collection
