Membership lapel-pin: 'Reichsbund der Körperbehinderten' (or: 'RBK') being a non-maker-marked example that is executed in multi-coloured, enamel

This is an attractive membership lapel-pin (ie. 'Mitgliedsabzeichen') that signified membership within the: 'Reichsbund der Körperbehinderten' (or: 'RBK') being a very detailed- albeit non-maker-marked example (that does show a: 'Ges.Gesch.'-patent-pending-designation) and that is executed in typical multi-coloured, enamelled: 'Buntmetall' and that comes in an overall very nice- (and I deem only moderately used- ie. worn-), condition. The badge shows the 'RBK'-logo coupled with a swastika-sign - and has I deem never been cleaned nor polished and still retains a truly nice and only slightly darkened- ie. tarnished, age-patina. This example comes mounted onto its still functional pin- ie. pin/catch-set-up. A similar badge is also figured in the 'Heering-Hüsken' lapel-pin-catalogue, wherein it is given a unique reference-number (5505A). I deem this is a most certainly decorative badge which I have priced according to its truly nicely preserved condition!
