A third full-size version of Physical Energy was cast in bronze in 1959, from the gesso model used for second cast. It differs slightly: for example, the rein appears on the right, like the first cast, rather than on the left, like the second cast. The British South Africa Company arranged for the statue to be cast at Leonard Grist's Corinthian Bronze Company foundry in London. It was originally located in front of the High Court building in Lusaka in Zambia. It was moved to a racecourse on the outskirts of Salisbury, in Southern Rhodesia (now Harare, in Zimbabwe). Since 1981, it has stood in the grounds of the National Archives in Harare.
