The Duiker II and Duiker III gas masks were Dutch civil defence masks (volksgasmaskers) produced just before WW2. They were designed by technical bureau J. Duiker, which is where the name originates from. The masks were produced by Hevea and Vredestein. At first, Duiker sold the masks themselves in small boxes, but later Artillerie Inrichtingen (the state-owned arms manufacturer) took over, and distributed them in orange metal boxes. The masks were for sale to the public, and were given to the Air Defence Service. (Luchtbeschermingsdienst)
Mask overview
The mask has a blueish-green or dark green rubber facepiece with a guarded flutter valve below the filter and a 5 point head harness. The filter may contain asbestos. The mask didn't come with anti-fog inserts and didn't have tissot tubes, so it would fog up. The mask comes in 3 sizes, 3 being small, 5 being medium, and 7 being large. The kit costed fl 6,50.
The only difference between the Duiker II and Duiker III kits was the different filter, and the round strap pieces that connect the straps to the mask were black on the III and brown on the II.

Kits
Model 130
The model 130 was the successor to the Model 128. It used the Hevea Duiker III facepiece that was being produced by Hevea already for civillians and civil defence. The new filter was an improved filter, made by N.V Electro zuur- en waterstoffabriek. The mask was sold in a rather large canister, to accommodate the large filter. The kit also came with a manual.
