Their busy day finds them focusing on a one-off clock made for the Great Exhibition in 1851, a painted portrait that looks modern and which has an astonishing valuation and a plain kitchen table which turns out to have quite a story, having been used as the campaign headquarters for Mary Whitehouse's Clean Up TV campaign.
