The Cessna 120 was an economy version of the 140 produced at the same time. It had the same engine as the 140, but lacked wing flaps. The rear-cabin "D" side windows and electrical system (radios, lights, battery and starter) were optional. The 120 was dropped from production upon introduction of the 140A in 1949. Despite these improvements, sales of the 140 lineup faltered, and the 140A comprised only seven percent of overall 120/140 production.
