Dave and Steve head to an auction house in Ludlow where they think they've spotted something rather special coming up for sale. It's a First World War pilot's logbook, but they're not the only one on the trail of this pilot's story… The team get their hands on some rare Waterloo medals, and a trip to the National Army Museum uncovers an extraordinary link between the medals and an iconic battle. And Dave and Steve go on a shopping trip to Hereford where they hope to buy some rifles from a collector.
