 FAKE: When Indy and Sallah go to see the old man to interpret the  markings on the headpiece to the Staff of Ra, the old man says that  the height of the staff is "6 kadam", to which Sallah replies,  "About 72 inches". This would mean that a "kadam" is roughly  equivalent to one foot. Then he turns the headpiece over and  finishes by saying "and take back one kadam to honor the Hebrew God  whose Ark this is", meaning that the staff should be roughly 5 feet  long. However, when Indy plants it in the map room and the light  hits the headpiece, the headpiece towers over him. This would make  the staff roughly 7 feet long.
