AB Flygindustri was founded in January 1925 and set up shop in a former shipyard on the islet of Ön in Limhamn near Malmö. 82% of the share capital was owned by Junkers which used the Swedish firm to circumvent Allied restrictions imposed on German aviation. Some of the buildings here still exist. S-AAAR to P-PAWA not taken up, to Lufthansa as a landplane, D-915 Wotan. The Junkers F13 S-AWAA was used by AB Aerotransport.

The G24 trimotor was sometimes referred to as the G23 to circumvent a ban by the Allied powers. Three examples were registered in Sweden for the same reason. They were sent to Junkers' Dutch affiliate NWM which was active in the second half of 1925, although Dutch registrations were not taken up. The aircraft then went to Lufthansa and S-AAAM became D-878 in December 1926. Allied worries were not entirely unfounded because D-878 soon served at the secret German military flying school in Russia. Photo by: Walter Hahn / SLUB / Deutsche Fotothek
