	Egyptian Shaduf
      
      
       
      Size: 14 x 6 x 32 cm 
      Crank mechanism 
       
      In Pharaoh´s times: The Egyptian peasant eagerly lifts the water from
      the Nile to his high-lying field, while the crocodile is attending its chance.
      A wall painting of this shaduf can be visited in the tomb of the noble Ipui
      in Theben West, 1240 B.C. Nowadays they mostly use motor pumps.  
       
      In reality the counter weight of Nile mud helped to lift the water. In
      the model the rotation of the crank is converted into the oscillating motion
      of the shaduf lever, the jaw of the crocodile will be opened by a bell crank
      lever.
