The Zivilschutzmaske Z 56 was produced by both Dräger and Auer (Auer version located here). The design was later licenced to Shalon Chemical Industries and manufactured by them in Israel (an example of the Israeli Z 56 can be found here). Both an early and later example of the Dräger Z 56 are pictured with the only difference being the package design. The Z 56 was made in 3 sizes, 1, 2 & 3 (large, medium & small). The early example pictured is a size 2 (medium) and the later example is a size 3 (small). The last image is of a spare filter with its box (Part No. RM 7970).
