Antiques Roadshow: Abbey Pumping Station 2

A return visit to the historic Abbey Pumping station in Leicester, now the city's Museum of Technology, which complete with four working beam engines is a fine example of Victorian engineering. Expert Ronnie Archer-Morgan swoons over some 1960s steel sculptures, while books specialist Rupert Powell meets playwright Joe Orton's sister who brings in the typewriter on which he wrote some of his most important scripts. Plus, Amin Jaffer discovers a valuable collection of exotic metal boxes - they look like snuff boxes but their actual purpose is much more intriguing. Presented by Fiona Bruce
