The British Armed Forces Military GSR Gas Mask is a collectible piece of militaria from the United Kingdom. This listing includes two filters and Gasmask Haversack. The interior of the haversack has been written on by it’s previous owners. The included filters have likely expired and as such shouldn’t be used with the mask for safety purposes. The mask is in good condition and would function fine if you are able to source replacement filters. The interior drinking straw is not present in this listing.
