SA (Sturmabteilung) Members Pin (Mitgliedsabzeichen). The SA (Sturmabteilung) was originally formed in August 1921 as a protective guard unit for the political leaders of the NSDAP. The pin is nicely maker marked by the company of 'Berg & Nolte' from Lüdenscheid and 'ges.gesch' marked on the back. Nice example in used and worn condition!
