Fiona Bruce and the team head for the races as they arrive at Chepstow Racecourse in Wales. Family treasures featured include medals from early Olympic Games, awarded when tug-of-war was a competing sport; a light bulb containing a painstakingly-made model of Lincoln Cathedral gifted by a German prisoner of war in World War 2; and perhaps the oddest and one of the oldest pieces of glass ever featured on the programme, which excites curiosity for its near-perfect condition over three hundred years after it was made.
