Presented by Alan Herd and Eric Knowles. At Andrew Grant Fine Art Auctioneers in Worcester, they purchase a set of six early Victorian mahogany balloon back chairs. Alan has to copy and make a replacement top rail on one of the chairs – can Eric spot the repair? Alan sends them to a master upholsterer in Nottingham to learn about modern and traditional techniques. The chairs were sold at Roseberys in London.
