The looting of these contents was described as M-Aktion (Möbel-Aktion). These claims were therefore known as Möbel-claims or M-Claims. The files contain several documents, including application forms, computation forms, statements of the right to inheritance and in several cases an Abnahmeverzeichnis or Inventory.
