Following development of the four-seat Model A the company designed a six-seat aircraft, the Model CW-6. The aircraft first flew in November 1928, powered by a 220 hp (164 kW) Wright Whirlwind J-5 radial engine. The aircraft was displayed at the 1929 Auto Show in Wichita, Kansas. A scaled-down four-seat version, the Cessna DC-6, was also developed.
