Peterborough

Presenter Tim Wonnacott gets to grips with a 2,000-year-old sword, discovered by a farmer in the River Nene in 1983 and now housed at Peterborough Museum.

Bargain hunters at the town's Festival of Antiques also try to spot treasures which have gone unnoticed, helped by experts Anita Manning and Charles Hanson. Among their finds are a Wedgewood platter, a seed pearl necklace and a figurine.
