Rare Reichsluftschutzbund (RLB) officer's visor cap. Hand-embroidered cap insignia. Both attached by hand and showing the same sort of light corrosion. Seems to be absolutely matching to this cap. Zinc cockade. Silver wire leader's piping.
Water resistant liner. No damage to the celluloid diamond. Nice maker's logo of HEINRICH BALKE MÜTZEFABRIK BREMEN. "Deutsche Wertarbeit". The symbol of the city of Bremen.
