Continuing their tour of Kent, Raj Bisram takes on a mighty mollusc in Rye, where scallops are king, while Natasha Raskin Sharp pushes the boat out on the Royal Military Canal for a closer look at the coastal defences designed to see off invasion from France. Raj nets a post-Napoleonic French eagle while cherubs and art deco costume jewellery are more madame's style. But despite heading for an antiques and fine art sale, Raj can't resist the risky purchase of an old oak coffer, which empties his pockets. Natasha splashes out on an expensive whisky noggin. Which of them will clean up at the Colchester sale?
