This cute little parasol wing aircraft was designed as a single-seater aerobatic sports plane.  Some
                                   22 were built between 1933 and 1937 and used by various aero clubs in Poland until the outbreak
                                   of war in 1939.  This is the prototype, and was discovered to be a little unstable, and hence
                                   production models were modified with a lengthened fuselage and other slight changes.
