Fiona Bruce introduces a return visit to Durham Cathedral, where treasures include a missionary's medical kit, an early etching by Dame Laura Knight and a beautiful carriage clock discovered on a Second World War bombsite. Fiona Bruce admires a remarkable collection of rare books in the cathedral's collection, including a 7th-century bible and an early version of Magna Carta, while ceramics specialist John Axford is charmed by a late 19th-century plate whose childlike decoration belies its value. The team appraise a rather gruesome 19th-century medical kit used by a missionary in Africa who followed in the footsteps of Stanley and Livingstone, and an early etching by renowned artist Dame Laura Knight. Clocks and watches specialist Ben Wright is amazed by the story of a beautiful engraved and gilded carriage clock that was discovered in a pile of rubble on a bombsite in Durham during the Second World War. Family treasures include football mementoes belonging to a man who played for Sunderland in 1913 and a collection of medals awarded to a young RAF navigator in World War II, now the proud property of his young grandson.
