M10 gas mask in bag, sealed filters, extra lenses etc ( NO DRINKING STRAW)

Description M10 Gas mask in bag, probably Czech in origin. This gas mask set contains: Bag ( canvas or vinyl, grey OR green in colour) Filters (sealed) Fixings for Filters Extra lens covers (clear) They are NEW/UNISSUED and have been in storage for some time. I believe the filters provided with these may have primarily been intended for tear gas type agents but I’m not 100% sure of that. Interesting collectors item. Please note that these gas masks and filters should not be considered as a working item of protective equipment.,
