'Reichsluftschutzbund' (RLB) Members Pin (Mitgliedsabzeichen), 1st model. The RLB (Reichsluftschutzbund) was an official national organization tasked with all aspects of civil air raid defence. This is the smaller 17mm version of the members pin. The badge is nicely marked with "Ges. Gesch." and maker marked by the company of 'Hofstätter' from Bonn. Nice example in good condition!
