However, a set of 1930s hat moulds captures his hat-lover heart.In amongst the shopping, Ochuko finds out about the young postmaster who went on to create one of the country's best loved cities, while Margie looks after Britain's most precious historical objects and gets up close and personal with every antiques expert's worst enemy.Who will rise to triumphant victory at the final auction?
