Thank you for viewing. This is a British Army gas mask made by AVON. It has a 1986 stamp. Size is 2 (M). I purchased it about 10 years ago and have stored it in a dark place. Although there is no significant rubber degradation on the facepiece, the strap feels slightly sticky. As it is a real item, there are scratches and scuffs on the plastic lens. This item is rarely seen nowadays, so how about it if you like it? Gas mask with bag.
