Fire helmet from Germany. The leather helmet shown here is probably one of the most leather helmets built in Germany. The helmet arose after the first world war. It was derived from the M15 used in the German Army. The army helmet M15 was often converted to a fire helmet. The helmet has a brass comb, the brim is covered with brass, the side cockades for fastening the chin strap are also made of brass. Interesting is the stamp inside:
Hermann Koebe - Fire brigade equipment factory - Luckenwalde.

From Wikipedia: After the abdication of the king in the autumn of 1918, Saxony became a free-market in the German Reich, which was called the Weimar Republic after setting the constitution in 1919. Since 1990 Saxony is a country of the Federal Republic of Germany.
