Austrian police say they cannot trace five Stradivarius violins, four Guarnerius del Gesu and eight other precious instruments, as well as valuable bows, that were supposed to be in the possession of the controversial dealer Dietmar Machold.
Machold was arrested in Switzerland five months ago and faces extradition to Austria, where he is accused of embezzelement and fraud.
The instruments were thought to be his collateral against creditor demands. An international search has been called. Here is a police list of the wanted instruments, supplied by Ariane Todes, editor of The Strad.
