Smith & Wesson No. 67 Gas Mask
The MSA All-Vision Gas Mask was made for a variety of applications, including law enforcement and industrial use. This particular version, sold as the Smith & Wesson No. 67 Gas Mask, featured two cheek exhale valves, a central speech diaphragm, and a chin-type canister to protect against CN, CS, and DM tear gas. This example was made by Mine Safety Appliances in 1966.
