In Stradivari's footsteps

Cremona in northern Italy is the home of the Stradivarius violin and 280 years after the death of the venerated violin maker, Antonio Stradivari , the long tradition continues today. In some 150 workshops around the city dedicated craftspeople make several thousand violins a year and they sell at high prices. Peter Day asks what the role is today of this kind of handwork in the age of mass production.
