Check the listing for details. Yugoslavian M-1 Military Gas Mask - Size Small. Condition: New. Listed at 49.00 USD. Genuine Yugoslavian M-1 Gas Mask marked for military issue but never used. Marked "M" which I can safely assume stands for "mali" or "small". Comes with original filter, canvas satchel, technical paper with information written in Serbian in the Latin alphabet, cleaning cloth, and anti-fogging cloth. This is still sealed but due to age I can not guarantee a perfect seal. Filters will still provide particulate protection (good for biological threats, dust, tear gas, and such) but may or may not still protect against vapour threats (such as most chemical weapons). As far as my research has discovered the filter does *not* contain asbestos so it should be perfectly safe to breath through however it is still an old filter and I have not done laboratory testing so take caution and ensure there are no leaks prior to any use.This is sold as a collectible, use at your own risk. Thank you for viewing and have a great day!
