The Pirelli M.24 was a mask produced in Italy for the Belgian army.
Mask overview EditThe face piece of this mask is made of leather, with two single-layer glass eye pieces. It uses a 7 points head-harness, with one of the straps connecting to the intake-outtake piece in the front, which have a metal pipe for attaching a hose. Inside the maks, there is a Tissot system to prevent fogging. The hose itself was made of leather, but in later use it was abandoned in favor of other kinds of hoses.
Filter EditThe filter was a large metal box containing the various blocking substances. At the top there was an angled tube assembly, and the bottom could be closed using a lid. The filter was always kept in the satchel and was connected to the mask via the hose through the angled tube assembly.
Kit EditThe mask came with its hose, filter, pamphlet and spare lenses inside a large, two sectioned sqare satchel. The hose was made of leather, but in later used a rubber hose was used.
History EditAt the beginning of the 1920's the M18 was outdated and the Belgian army was in need of a new mask. Because of the small funds, rubber was ditched and leather was chosen; the army also chose to go for a larger filter connected via a hose. The company who got to make the new mask was Pirelli. The leather used was high-quality and overall the construction was refined, but the mask had three major problems: firstly, the glass was easily breakable, rendering the mask useless in a combat situatuion; secondly, the exhale valve was not very efficent and soldiers used to break it to make air flow easier; thirdly, the sheer weight of the intake-outtake piece made the mask fall from some soldiers' faces. Because of those problems, the army decided to switch to a new mask in 1929, again made by Pirelli.
