Siebel Fh 104 Hallore

what is it?

The Siebel Fh 104 Hallore was a small twin-engined transport, communications and liaison aircraft designed by the German aircraft manufacturer Klemm Leichtflugzeugbau and produced by Siebel. The Fh 104, which was originally designated Klemm Kl 104, represented a considerable departure from Klemm's previous aircraft designs, being largely composed of metals, such as duralumin, instead of wood and fabric. While the fuselage was mostly made of duralumin, the wing was primarily composed of wood.
