Remarkably the large Artificers Guild silver and copper biscuit box I have for sale has just come to light in a BBC documentary on modern Britain. An identical box (conceivably this one) features in a c 1960 film clip of Prime Minister Harold Macmillan’s office in Downing Street. It can be seen on the table behind him in “other images” of my product write-up at this link.  This clip is from the BBC’s documentary “A history of modern Britain”, second episode. Thanks to Dave at for spotting this!
