Can I highly recommend to all and sundry the series Industrial Revelations and More Industrial Revelations on the Discovery channel hosted by Mark Williams ex Fast Show and Harry Potter. He makes a highly entertaining, enthusiastic and informative presenter. This is a most interesting show that I defy anyone not to find of value. It explains every facet of our industrial past, the men and the machines (most of them very big and steam-driven) that made the empire. It is repeated on Discovery quite regulalrly but unfortunately not yet available on DVD. For anyone with kids this is the perfect antidote to current 3rd Reich obsessesed GCSE history syllabus in showing what this country is/was capable of.
