However, after World War II the Governor of Tanganyika, Sir Edward Twining, took up the issue again. After enquiries he was directed to the Bremen Museum which he visited himself in 1953. The Museum had a collection of 2000 skulls, 84 of which originated from the former German East Africa. He short-listed the ones which showed measurements similar to surviving relatives of Chief Mkwawa; from this selection he picked the only skull with a bullet-hole as the skull of chief Mkwawa.
