Tim Wonnacott takes his old rig along to Cambridge and sets up at the Cambridge Town and Country Show, where lots of eager owners have come along to show him their fascinating items, including fen skates, a vintage radio and a collection of old bottles, some of which are surprisingly rare and valuable. Tim visits Cambridge School of Art and hears about the work of one of its alumni, celebrated illustrator Ronald Searle. And he investigates the hoard of Tudor relics found in one of the university colleges.
