Thomas Forrester shows Charlie a collection of rare and valuable examples, including detailed early designs and specimen notes. It's all about the money too for the red and blue teams as they battle it out for bargains at an antiques centre near Stratford-upon-Avon. Best friends Sandra and Florence and their expert Tim Weeks go head-to-head with father and son Jason and Andy and expert Izzie Balmer. Will Andy's love of toy cars outmanoeuvre Sandra's passion for teapots? Over in Lichfield, what will auctioneer Richard Winterton make of the teams' lots? And which team will make the most profit and win the day?
