None of the Stradivarius violins are in their original condition (not even the "almost never been played" Messiah Stradivarius). There was a time where Baroque violins would get their neck removed and re-glued at a larger angle, along with a bridge replacement. This happened to every single Stradivarius ever made. And then, there's the shift to modern steel strings. And most of them have been opened multiple times to seal cracks in the wood.
