Association (THK) was an aircraft manufacturer from 1926 to
1952. THK designed and manufactured about 18 different types of
airplanes and sailplanes. Some of the types were produced under
license from French, British, German, and Russian designers.
THK-3 was a sailplane originally designed by Deutsche Forschungs-
Anstalt für Segelflug (DFS) of Germany. THK manufactured six of
this model by reverse engineering of the original German model (DFS
Habicht). The documents presented here are taken from the THK's
Sailplane Registry Notebook for the No. 1 aircraft which left
the factory on 30 July 1945.
