Thanks Reichssammler for the translation.
A Eyewitness (Frau Rantz) has told that the furniture of the Reichskanzlei was stored in Castle Augustusburg in the Erzgebirge since 1944/1945.
So it looks like most of the furniture from the Reichskanzlei, including Hitler's desk, was removed from the building and placed in safe storage before
the Soviet offensive on Berlin.
This would mean that the desk in Hitler's study which was broken up by Russian soldiers for souvenirs in May 1945 was probably a low-quality replacement and not the magnificent desk seen in photographs earlier on in the thread.
Also, the furniture from Hitler's private quarters in the Fuhrerbunker was low-quality - cheap wooden tables and chairs. The expensive furniture, tapestries and paintings had obviously all been removed to protect them from the Allied air-raids on Berlin and the impending Soviet offensive.
This would explain why so little "war booty" was recovered from the Reichskanzlei by Allied troops after Germany's capitulation.
