The Kl.107 low-wing, wooden-framed monoplane trainer was designed in Germany during World War II. Early versions were powered by the Hirth HM 500 100hp engine, and only a small number were completed before the factory was erased by Allied bombing. In 1956 it was decided to reintroduce the Kl-107 as a civil training/touring type, initially as the Kl-107B, but then as the three-seat Kl-107C. Rights to the design were acquired by what became the MBB consortium, and the final version became the Bo.207.
The Bolkow F.207 second prototype development of the Kl107C, originally called the Klemm Kl 107D, first flew on 21 April 1961, from Stuttgart-Echterdingen airport.
