Rotative steam engine by Boulton and Watt, 1788. Boulton and Watt Rotative Beam Engine - the 'Lap' engine. This is the oldest essentially unaltered rotative engine in the world. Built by James Watt in 1788, it incorporates all of his most important steam-engine improvements. The engine was used at Matthew Boulton’s Soho Manufactory in Birmingham, where it drove 43 metal polishing (or ‘lapping’) machines for 70 years. © The Board of Trustees of the Science Museum.
