'Nationalsozialistischer Deutscher Frontkämpferbund Stahlhelm' (NSDFBSt) Members Badge (Mitgliedsabzeichen). The badge is maker marked on the back with 'W.D. Ges.Gesch.', most likely indicating production by the company of 'Wilhelm Deumer'. The badge comes on its original and functional buttonhole attachement. Nice example in good condition!
