Today's location is the Mona Showground on Anglesey. Presenter Anita Manning is in the driving seat and the experts are Caroline Hawley and Philip Serrell. A married couple take on two newlyweds to buy three items that will hopefully make a profit at auction, and they all have their sights on a Golden Gavel. Anita takes the baton to conduct the Holyhead Male Voice Choir and tells the intriguing story of what was known in the 1930s as the world's smallest camera.
