German Mask Zivilschutzfilter 68 Civil Defense The Zivilschutzfilter 68 is a mass-produced West German Civil Defense filter, developed/put into production during the Cold War. I do not know if the canister is functional and am offering it as a piece of display militaria. That being said, it is in excellent cosmetic condition. The canister reads "Zivilschutzfilter 68" and has the letter "C" and the number 70 over 5113 stamped on it. The rubber of the mask is supple and the fasteners are all intact, as is the glass for the eyes. The mask has an "M" stamped on it as well as what looks like an SW logo inside of a triangle.
