German Wehrmacht GM38 Gas Mask Removable Lenses Keeper Ring, Inside Mask.

Sometimes this ring is missing from the mask. It is for keep the detachable lenses in place, when you need to change the used lens, you remove the ring and you can then chane the old lens by a new one, putting back the ring after that. This ring is to be used with the mid-late war green or black rubber made model, not with the "cloth" Feldgrau masks.
