The show comes from the Bowes Museum at Barnard Castle in County Durham. The museum was purpose-built to house the collection of Josephine and John Bowes, and in the picture galleries, experts Paul Laidlaw and David Harper pick out some gems to value. They include illustrated books by Arthur Rackham and Edmund Dulac, and a carved dog's head. Presenter Paul Martin investigates the museum's latest conservation techniques.

This episode comes the National Maritime Museum, Cornwall based in Falmouth. Antiques expert Philip Serrell finds an unusual tortoise with an excellent pedigree and Caroline Hawley takes an electric guitar to auction which plucks at the heart-strings of the bidders. And Paul Martin goes deep underground to uncover Cornwall's industrial past.
