The T.33 is the successor to the P.C. 30. It is the 5th gas mask approved by the S.C.M. (Servizio Chimico Militare, chemical military service) on 31 August 1934.
Mask overview Edit
This mask was considered a great step forward from the P.C. 30 because it used a slightly better strap system, the rubber was more confortable and the filter used better blocking substances. The face piece was made with stamped rubber of varying colours. It has two "unbreakable" glass eye pieces that sport a metal ring for putting on anti-fogging lenses. The exhale valve is in the front and it's covered by a removable lid for protection. The filter intake is at the bottom. The inhale valve is a rubber disc just above the filter intake. The mask uses the standard Italian five straps system, four of which are elastic.
The mask came in a metal cylindrical box that contained the filter, the instructional pamphlet and the mask itself.
The filter used with this mask was brightly coloured for its use with civilians and had the same typical shape of the T.35 filter that would come 2 years later.
