The Optische Gasmaske is a German interwar and WWII-era optical gas mask based on the Leder B-Maske. Mostly and incorrectly known as GM44.

Overview[]

The German optical gas mask (literal translation of Optische Gasmaske), is a Dräger mask made from a leather facepiece with a fabric and leather head harness and has an intra-ocular adjustment rod for the small circular eyepieces, a similar design to the US MI optical mask. The Optische Gasmaske is based off of the Leder B-Maske.

Behind the eyepieces are eyecups which aided the wearer when using binoculars. Like some of the rare variants of the GM30, the Optische Gasmaske has a threaded microphone inlet that can be closed when not in use. The plug may have an additional outlet valve installed in it.

It had two types of harness. The earlier is similar to the one on the Leder B-Maske while the later one is closer to the GM24 type.

Filter[]

A rubber hose (either natural rubber, natural rubber with stockinette or Buna-N rubber) is used with the mask and positioned so it can be worn over the shoulder and the filter attached to the back. The filter is either a large box type GM24 or the FE 41 type.

Kit[]

There are two different containers the mask was stored in, a green Dräger container and a wooden one. With every optical mask issued there were a set of four eyepiece adapters for use with various equipment.

The Opt. Gm. is thought to have been used by Kriegsmarine and Wehrmacht.
