The Siebel Fh 104 was designed by Klemm Leichtflugzeugbau as a small, light high performance passenger and mail transport, and rapidly developed into a fast general liaison aircraft, with such personalities as Adolf Galland, Albert Kesselring and Ernst Udet flying them.
It was developed by in their new factory in Halle, (hence the name "Hallore", nick-name for the inhabitants of Halle), which was transferred to Fritz Siebel and became Siebel Flugzeugwerke in 1937, the year when the prototype first flew.
It had a metal fuselage, plywood covered wings and a hydraulic, retractable undercarriage. Its performance was higher than many of today's executive transports, and was also used for record breaking and racing, notably by Ernst Udet. Fh 104s' won long distance flying competitions in 1938 and one unit flew 40,000 km around Africa in 1939. It won the principal award in the 1938 Littorio Rally.
At least 15 aircraft appeared on the pre-war German civil register. It was produced until 1942, 46 units being built, and was the basis for its successor, the larger Siebel Si204.
