Davis Type M-1 Gas Mask
The Davis Emergency Equipment Company Type M-1 used an orange molded rubber facepiece based on the Kops Tissot Monro (K.T.M.) design. The M-1 features a 10 inch hose leading to a 650cc filter canister. The mask is marked with the Bureau Of Mines stamp "B M 1408". It was stored in a metal box with the Davis logo on the front, and instructions for use on the inside cover. This example was made in 1935.
