Austrian authorities investigating the violin dealer Dietmar Machold have published a list of instruments and bows they want to trace in connection with the case. The instruments are believed to have been consigned to Machold for safekeeping, or used as collateral for bank loans. The list includes five violins by Stradivari and three by Guarneri 'del Gesù', as well as the latter's only known cello, the 1731 'Messeas'. The full list is available here.
