The roadshow team visit Roundhay Park in Leeds, where treasures include family photos of Arnold Schwarzenegger, a psychedelic chair, an original script for Dad's Army and a mysterious diamond ring. Elaine Binning is thrilled to see a plastic chair from the 1960s with a psychedelic colour scheme, while Susan Rumfitt admires a mysterious diamond ring that could date as far back as the 17th century. Paul Atterbury hears the bizarre tale of the London bus that "jumped" over Tower Bridge as it was opening and finds out how a little girl got the chance to meet Winston Churchill on a flight from France in 1953. Clive Farahar is intrigued to see a collection of family photos documenting a visit to Leeds by Arnold Schwarzenegger during his early days as a bodybuilder, and he also gets the chance to appraise a valuable script for an early episode of much-loved sitcom Dad's Army. Fashion expert Suzi Yang sees two fabulous dresses by 60s designer Ossie Clark, while Fiona Bruce hears the story of pioneering cyclist Beryl Burton, a Yorkshire woman who worked on a rhubarb farm and broke cycling records in the 1950s. Fiona also gets the chance to meet Joanne Harris, best-selling author of Chocolat, to hear her childhood memories of Roundhay Park and see a treasured antique that belonged to her grandmother.
