It’s the fourth leg of Catherine Southon and James Braxton’s road trip, and success at the last auction means one expert has double the kitty of their rival. There’s pride at stake as our pair head across Derbyshire and Leicestershire to an auction in Bedford in their stately classic 1969 Rover. The twosome’s shopping choices could not be more diverse. How do Catherine’s 18th-century caryatid carvings measure up against James’s very old bowl of marbles? And away from the antiques, Catherine gets steamed up on the heritage Great Central Railway, and James goes potty about pottery. It’s a romp and a half, and with a mix up over one item and a costly gamble on another, who will come out on top in the penultimate auction?
