It's the second leg of our riotous road trip, with Raj Bisram and Irita Marriott ambling around Northamptonshire.Irita takes it easy with her spending spree, picking up a very unusual B&B sign and an early 20th-century Japanese Satsuma pot. She presses pause on her shopping to discover the roots of a former slave-ship captain who penned the soaring spiritual Amazing Grace in the 18th century.On this tour of the south Midlands, Raj picks up a bevy of items, including a rather lovely art deco silver trinket box and a kaleidoscope dating from 1905. Our antiques guru makes a stop in St Albans to find out more about the only surviving medieval town belfry in England and just why it is such a source of civic pride for all St Albans locals.Who will swoop up the profits and clinch auction glory?
