Four Kriegsmarine "Würfelschlüsselzettel" message forms accompanied in a book of grid paper with "Kriegsmarine" printed on the front cover. These message forms were purchased from the grandson of Wilhelm Gotthardt, a Kriegsmarine Minesweeper Commander. His service record is written on the document, which was likely used as spare paper in the early 1950s in his application to the post-war German Bundeswehr. He was involved in clearing mines until November 1947. He refers to the German Mine Sweeping Administration (GMSA) which moved its headquarters to Hamburg in December 1947, but was then quickly disbanded in January 1948.
