Eric Knowles presents from Southwell Racecourse in Nottinghamshire. Experts David Harper and Gary Pe help guide the reds and blues as they buy three items with £300, which they hope will make a profit at the auction. The reds show David how to be cool, while the blues go in search of a duck-billed platypus. Eric also pays a visit to the Museum of Time Keeping to find out about a local man's mission to save the St Pancras Railway Clock.
