Possibly post-war Neo-Nazi badge related to the exile German associations of Silesia. The motto Denkt An Beuthen , or "Remember Beuthen" refers to the Silesian city, now Bytom in Poland. The German population of Silesia was essentially forced out after the area was ceded to Poland after WW2. During the 1950s, various "Homeland" associations were formed and some took on Neo-Nazi character and would eventually be banned.
