Junkers EF031/4 Mockup, Summer 1928
The EF031 was a twin seater Sport aircraft of 1927. At least four different designs EF031/1 to EF031/4 were presented between January and April 1928. In May 1928 an EF031 mockup was presented, but another EF031/5 was designed. In October 1928 the EF031/5 became the Junkers J50, which later became the Junkers A50.
