This amazing creation is referenced in at least one edition of Jerry Slocum's book "The Cube" and in Christoph Bandelow's book "The cube and beyond" and in a german newspaper article about Christoph Bandelow, dating 5 Dec 1981.
All three credit Jürgen Hoffmann with creating a functional 5x5x5 out of brass.
According to the newspaper article it weighs ca. 7 kilograms.
It seems that Jürgen Hoffmann never patented his invention which allowed Udo Krell to become the real father of the mass produced 5x5x5s.
