Post-World War I disarmament caused a decrease in military construction development. Military aviation was coming through the time of stagnation as civil aviation dictated technical progress. The golden era of its development fell on the 1920's and 1930's. The numerous new companies, producing cheap, simple and reliable machines, appeared.

The Bücker Bü 131 Jungmann aircraft was designed in 1933, by the Swedish constructor Anders Anderson working in Germany. The machine was a school and aerobatics plane, a two seater of mixed construction. The airframe featured a steel tube welded fuselage, wooden wings and a fabric skin. First flown on the 27th April 1934, it was the first product of the newly created Bücker Flugzeug Werke. The machine was characterized by small dimensions and good aerobatic abilities. From 1936, the Bü 131 B powered with the Hirth A2 engine was produced.

The aircraft rapidly entered aeronautical and aerobatics schools, not only in Germany. Before the outbreak of war, the Jungmanns were the basic machines of the German aeronautical schools. They were exported to many countries and were built on licence in Spain, Japan, Switzerland and Czechoslovakia. In the years preceding the outbreak of World War II they also took part in international competitions, i.e. the 1938 South African Round Reef Race. They came third during the 1938 Aerobatics Championships in Holland.

In 1935 a smaller, single seat version, powered with a radial engine, (the Jungmeister) was introduced into production. The aircraft in this variant were built in Germany, Spain and in Switzerland. In 1938 numerous aerobatics competition victories were achieved on the Jungmeister. The last examples were built in Germany in 1969.

After WWII, through almost 25 years, the Jungmanns and the Jungmeisters aircraft were one of the most popular aerobatics aeroplanes of the world. Many of the machines had their engines changed to more modern and more powerful Lycoming engines. The airframes with these engines were assembled in Switzerland under the Bü R-171 designation. Many Jungmanns fly to this day.

In Poland, two aircraft of this type were registered before the war, and another two ex-German examples were in service after the war. Currently, a company called the Polish Historical Aircraft Service Co. in Bielsko builds the Bü 131 Jungmann. They are not replicas, but certified licence aircraft. The technical changes in comparison to the pre-war construction, comprise the use of the most modern materials and different engines. These machines became very popular and the company received many orders for many years to come.

The aircraft on display, the Bücker Bü 131 Jungmann serial number 13.113 (SP‑AFO) was taken over in 1945 and after repair at the District Aviation Works in Poznań flew at the Poznań aero club in 1946–1955. After retirement, it was delivered to the Museum in 1963.
