Antiques Roadshow: Knebworth House

Series 24, episode 0

Michael Aspel and a team of experts examine curios and artefacts offered up by the public at Knebworth House. This week's treasures include a diamond brooch which almost went to a car boot sale, a marine chronometer left to the owner by a drinking pal, and a bronze 'spirit of ecstasy' which, if genuine, could be worth 10,000 pounds.
