The RLB was in charge of educating and training ordinary German men and women in civil defense procedures necessary for the basic level of local self-help of the civil population against air raids. The local level was formed around air raid wardens and operated in small first intervention squads. The training included firefighting, protection against chemical weapons, communication procedures and preparation of houses and apartments against air raids. This armband is most likely unissued as there is only some minor soiling and handling wear and a few small stains.I have added some photos taken under a black light to illustrate the fact that the fabric does not glow as would most post war manufactured cloth items. Also, pictured are the stamps with appropriate inspection markings and regimental information. Great example of a very difficult to find variation!
