Antiques Roadshow (UK): Season 38, Episode 24

38 - 24: Trentham Gardens

Treasures include rare items from the region's historic potteries, a brooch that belonged to flying ace Amy Johnson and a portable road map described as an early form of satnav. Jewellery specialist Susan Rumfitt challenges Fiona to spot the odd one out among a collection of gold necklaces and bracelets - one of which is actually made from a cheap imitation alloy known as pinchbeck.
