The only Tanzania-based hunter invited to join the group was Derrick Dunn from Arusha. Red-haired and powerfully built. Derrick was affectionately known to the Africans as Bwana Siagizi (Mr. Sleepy) because of the shape of his drooping eyelids. Dunn had taken up elephant hunting as a youth in Nyasaland (now Malawi), then moved to Tanganyika in 1956, and turned professional with Lawrence-Brown Safaris, before going into the safari business for himself. Derrick was awarded the Shaw and Hunter Trophy twice, in 1971 and 1972, the only man apart from Syd Downey to be so honored. On the first occasion Derrick's client, R. M. Zimmerman, obtained a 47 1/2 -inch East African sable antelope at Rungwa, Tanganyika. On the second Paul Deutz obtained the outright world record Cape buffalo (a bull), which measured 59 5/16 inches, taken at Maswa, south of the Serengeti. The record still stands.
