Eric Knowles presents the latest contest from Hemswell in Lincolnshire. Twin sisters Beth and Ellie are advised by Catherine Southon, while father and daughter Luzani and Syhann are led by Mark Stacey. All then head to up the county to North Hykeham, hoping to make some profits under auctioneer Colin Young. Eric's mystery item is from the 19th century. It can be made of pewter or tin, has a pumping action and a very tedious link to Lincolnshire history
