My gas mask collection is a part of my gas, chemical, nuclear and biological warfare collection which is mostly made up of manuals, books and a few chemical protection suits and that is part of my militaria collection which is made up of many different items from helmets to communications equipment. The gas, chemical, biological and nuclear collection started in 2004 where it slowly started, but in the last few years it has rapidly grown. I currently have around 40 masks, 2 complete suits and many manuals and books.
