'US military records confirm that in September 1948, the missing Polish Stradivari was found by Officer Stefan P. Munsing of the US Army, in the home of a former SS member, Theodor Blank, in Heinrichsthal, Germany. After an investigation, the following items were taken into US custody for restitution to Poland: "One violin (Stradivarius), one box, two violin bows." By October of 1948, records state: "The famous violin x already closed in Hesse", suggesting that the investigation had run its full course, resulting in the return of the violin to Poland. But the Polish Ministry of Culture state in 2008, "Our research had revealed that the Stradivari violin from the National Museum of Warsaw had never been returned to Poland." [...] its current whereabouts remain unknown.'
