🇵🇱 Polish MP-4 Gas Mask dated 1987, made between October and December. It is a size 2, and is in Factory condition with the Talc powder still on. The bag is a waterproof version, there is also a secondary clear bag that most Combloc masks utilized. The kit contains sealed filters, two decontamination kits, two filter caps, and an MP-4 Gas Mask. The MP-4 is a Military Gas Mask much like every other M17 Clone, it was later replaced by the Polish MP-5 in 1990, the MP-5 being a licensed copy of the French ARF-A. The 95 on the left side of the mask may be the lot number, but I am not entirely sure, the 87 is obviously the year, the 6 by the four dots is a mystery to me, and the 20/ is also a mystery to me.
