Nigel Havers welcomes four more sellers to the Bidding Room, where they try to sell items to five professional dealers who are on the lookout for interesting pieces, with help from expert Simon Bower. First up today is Dale with a bronze statue of a racehorse. With the market strong for equestrian pieces, will he make it over the finish line and achieve the price he wants from the dealers? James from Wolverhampton has brought in an online find: a 17th-century writing desk. On closer inspection, the dealers discover that not only does the piece have several hidden compartments, but the escritoire has also been adapted over time. Will this affect the item’s value? Andrew's item is something of a mystery. The dealers think his intriguing wooden box is Edwardian, but what was it used for? Lastly, Pauline from Leeds is selling a collection of commemorative Concorde service medals. She is keen to find out if these iconic pieces of aviation history have any value in the current marketplace. Today's dealers are Adi, Ian, James, Jane and Tash.
