09/30/2007. Remarks by Johan Visschedijk: "Until the works were taken over by the sport pilot Siebel the Flugzeugwerke Halle produced German aircraft under licence. The first own design produced by the Halle works was the five-seat high-speed passenger aircraft Fh 104.
The prototype was flown for the first time on February 25, 1937 and in all 46 aircraft were built, several were used as personnal transport for high-ranking Germans like Adolf Galland and Ernst Udet. D-IQPG was attached to the E-stelle at Rechlin."
