Italian Maschera Antigas Pirelli T.35
The Italian Maschera Antigas T.35 featured round glass eyepieces and a central speech diaphragm. They were designed for use by the Italian military, but many were exported to Spain during the Spanish Civil War. The second mask is such an example, equipped with a Spanish C.M.P. filter. Both of these were made by Pirelli around 1935.
