The oldest instrument in use?

On tonight's 'In tune', there was an interview with a violinist who was playing a Guarneri (sp?) violin which he said had been made in 1698. It sounded beautiful - and even I, who am no violin junkie, could tell that this instrument was something exceptional, with a fully rounded tone.

My question is this: here was someone playing a 310-year old instrument. I know most Strads are almost as old, but the exceptional age of this fiddle boggled my mind a little. Is this some sort of record? Or does anyone know of an older instrument that is played regularly - not just brought out of a museum case for occasional demonstrations, but is actually the daily tool of some instrumentalist's trade?

(Large pipe organs are a bit of a grey area; they are often restored, and certainly don't travel very far...)

The Ashmolean museumin Oxford has some old violins including the Messiah Strad, which is pristine as it has hardly ever been played. They also have some of the oldest violins surviving, made by Andrea Amati for Charles IX of France. Some authorities think that these instruments came to England at the Restoration, Charles II having been impressed by Louis XIV's "24 Violons du Roy" (typically 6 violins, 12 violas of three different sizes, 6 'cellos). One of the violins has a label with the date 1564, and may be the oldest surviving violin. Another candidate, with an identically dated label, is in the Tullie House Museum.

Also the Royal Academy in London has some old instruments.

I visited the musical instrument collection at the Metropolitan Museum a few years ago, and the docent informed me that some of the older instruments are still played in the concerts they hold there, though I don't know what the oldest is that has been used.

Now here's old! There's a link on this page to a recording of a neolithic flute!
