Fiona Bruce and the team pay a return visit to the magnificent Broughton Castle near Banbury in Oxfordshire. Objects exciting the team include two very large portraits depicting servants who worked at the castle in the 18th century, which art expert Philip Mould says are rare and sociologically highly significant. We hear the story of the man who is believed to have flown the first scheduled air service in Britain before signing up to be one of the first combat pilots in the Royal Flying Corp in 1914. And silver expert Ian Pickford is enthused by the arrival of the finest Chinese-made silver mug he has seen in over twenty years on the Roadshow.
