We did some research and we could find the followring info : During 1944-1945 in Markkleeberg, a forced labor camp for women was established in the town. Initially it was a subcamp of the KZ Ravensbrück concentration camp and later of KZ Buchenwald. In early April 1945 the surviving inmates were transferred to the KZ Mauthausen-Gusen camp in Austria. In wikipedia there's no reference to this pleace connected to Junkers! This is set of one person: 2 IDs ( one from camp) + letter "P" . Just see her photo, she has letter "P" on her breast, exactly the same "P" that it's attached for sale! Very rare set indeed!
