WITTEMAN. Witteman Bros., 17, Ocean Terrace and Little Clare Road, Staton Island, N.Y. These people do a considerable business building Curtiss type machines or machines to special designs for others. They built the _Baldwin_ biplanes for Captain Baldwin, to his design, using steel tubing throughout. See _Aeronautics_, December, 1911, for a _Witteman_ of special design shown by them at the Aero Show. [Illustration: Witteman. 1912-13.] WRIGHT BROS. Biplanes. The Wright Co., Dayton, Ohio.

Its special features were a biplane elevator forward, main planes with warpable tips to trailing edge, small keel in gap, 2 propellers, chain driven in rear of planes, double rudder in rear and no tail.
