German Leder B-Maske
The German Leder B-Maske was made of leather, and had two large oval plastic eyepieces. They were mainly used for industrial purposes. The first example features a UA filter connector, and was made by Dagerwerk Lubeck in 1935. The second example uses a ZA filter connector, and was made by Drager in 1957.
