J.Bruce British Aeroplanes 1914-1918 (Putnam)

The Ruffy-Baumann School Biplanes
  
<...>
  The first truly original aircraft built by the Ruffy, Arnell and Baumann Aviation Co. was a clumsy single-seat biplane powered by a 60 h.p. Anzani six-cylinder radial engine. This machine had single-bay wing bracing, and the fuselage was faired to a more or less elliptical cross-section. Ailerons were fitted to the upper wing only, and were actuated by a system of rods and cranks. The machine was described, somewhat optimistically, as an advanced training biplane.
