Carl Zeiss “Umbral” dust goggles with Ersatz material pouch

General purpose dust goggles or “Umbral” goggles as patented and produced by Carl Zeiss, Jena. The construction of the goggles and the pouch indicates that this is a late war production set. The goggles itself are made out of brown coloured leather.  The pouch seems to be made out of a brown pressed paper Ersatz material. Nice example of dust goggles!
