That one has been on the auction circuit for a while - the claimed origin has changed apparently. I do not think it is genuine, but it purports to be a distinctive Baltic type of hilt, from the area of Lithuania and Prussia. Several are decorated in a very particular style, as on this example in the Bargello Museum. (Note that here the Baltic hilt components have been combined with a much later blade.) The same style can be seen on a number of rare axe-heads. Vytautas Kazakevicius' book
IX-XIII a. Baltų Kalavijai has more information about these swords, which he calls the Desiukiskes type, after one of the find-places.
