A NEW SOPWITH-HAWKER MACHINE: The "Duiker" is a two-seater corps reconnaissance monoplane, fitted with Bristol "Jupiter" or Siddeley "Jaguar" engine. The machine shown in the photograph has the former engine. As the "Duiker" is built for the Air Ministry, no detail information concerning it may be published. Note the tapering wing, which is thinned down in the centre so as to give a good view. The machine was designed and built by the H. G. Hawker Engineering Co., Ltd., of Kingston-on-Thames.
