Overview: Bargain Hunt heads to the International Antiques and Collectors Fair in Ardingly where two teams get to scour hundreds of stalls. Mark Stacey leads a couple off to a great start before they lose their way, and James Braxton's team let a bargain slip through their fingers. Tim Wonnacott visits Portmouth Historic Dockyard. A collection of artefacts paint an interesting picture of what Admiral Lord Horatio Nelson was really like. At auction, Tim spots a winner.
