We meet the tennis ball makers of the West Country

Johanna Konta uses them...Andy Murray uses them..with slightly less effect today it has to be said... tennis balls of course.

Most are now made in the Far East. But there is one small factory in the West Country still serving them up. In fact it's Britain's only ball factory.

Price of Bath, a family-run business actually in Wiltshire, has been going for 80 years.

Bob Crampton has been watching them coming off the production line in the village of Box.
