MSA All-Vision Chemical Cartridge Respirator

The MSA All-Vision Gas Mask was made for a variety of applications, including law enforcement and industrial use.  This configuration was called the All-Vision Chemical Cartridge Respirator.  It had two cheek exhale valves and a filter canister attached directly to the chin to protect against tear gas.  This example was made by Mine Safety Appliances in 1969.
