Italian Maschera Antigas I.A.C. M.33 (Spanish Export)

The Italian Maschera Antigas I.A.C. M.33 was made of smooth dark brown rubber.  This version featured a metal inlet/outlet assembly, and was exported to Spain during the Spanish Civil War.  It was made by Industria Articoli Caoutchouc around 1933.
