British Mk IV Service Respirator

The British Mk IV Service Respirator was made of tan fabricized rubber, with round glass eyepieces and a central speech diaphragm.  It had a long corrugated hose leading to a large box filter.  The design was very successful, and copied by several other countries.  This example was made by Avon in 1941.
