The Humlan (Bumble Bee) is a single-seat autogyro, designed by Staffan Ekström and Helge Svensson. They had been testing various foreign autogyros for a long time and decided to manufacture their own. After extensive ground tests, the first test flight (SE-HXA?) took place at Barkarby in June 1973 with the type in production between I1973-1976. This example is now on display at Aeroseum.
