The Tora mantle had been given on loan to the Jewish Historical Museum in 1936; it was stolen by the Nazis during the occupation. The Israel Museum admitted receiving the cover from the Jewish Cultural Reconstruction, an organization established in 1947 to deal with the collection and redistribution of unclaimed Jewish cultural property.
It took about sixty years to force the Museum to produce a list of over 700 items that ended up in the museum by way of the Jewish Cultural Reconstruction.
