Swedish Gasmask Typ 4

The Swedish Gasmask BICAPA Typ 4 was made of green rubberized canvas with two large glass eyepieces and painted metal hardware.  The first two examples shown are equipped with BICAPA filters, and the third example is missing its filter and exhale valve assembly.  These masks were made by Birger Carlson & Co. A.B. in 1941.

Gasmask Typ = "Gas Mask Type"
