Heinkel He 100 from the left
Here we see one of the few Heinkel He 100s to be built in flight. The He 100 was then used in a successful deception effort to convince the British and French that it was actually a new fighter aircraft that had entered production, the Heinkel He 113. This entirely imaginary aircraft then appeared in many Allied reports, with Aircraft of the Fighting Powers for 1940 describing it as having entered production, and having a top speed of 400mph at 19,000ft and a wing span of 30ft 10in and length of 26ft 10in, which do match the figures for the He 100. Exactly why the new number was chosen for this deception effort isn't known.
