Teeth of Steel (S)

The mechanical power of giant excavators and the work they do to help Britain’s growth. 'Britain’s giant excavators with their teeth of steel are cutting new inland waterways, draining fenland so that more food can be grown, carving out railways, docks and harbours, hewing iron-ore for factories and shipyards, digging clay for bricks. These machines, perfected by British engineers, give their powerful aid to Britain’s reconstruction.’ (Films of Britain - British Council Film Department Catalogue - 1942-43)
