Airlift Dakota fuselage part location needed in Germany

A decade or so ago, a large chunk from a derelict Dakota Spanish at Sabadell (near Barcelona) was obtained by a German organisation. The fuselage part, about everything behind the wing including cargo doors and tail, was to be placed in a museum/building as a reminder of the Berlin Airlift. Last week I discovered the nose of the Dakota in a shop in Barcelona, but I am still trying to locate where the fuselage went to. In Barcelona I was told it was in Hamburg, while another source claim it is on show on or near the Reichstag in Berlin. Anyway, I can not trace it. Does somenody knows?
