Very nice and rare zinc Erkennungsmarke from a Belarussian member of the weissruthenisches Schutzmannschaft-Freiwilligen-Bataillon 64.
It was formed in 1944 and later absorbed into Schutzmannschaft-Brigade Siegling, which was later used to form the 30th SS division.
It is very rare to find original SchuMa tags.
Many of these units were involved in the Holocaust. The condition of the tag is very good.
