Displayed at Harrogate in 2009 were these excellent models of engines from the earliest days of steam. Unfortunately we do not have the builder’s name, they were exhibited by the Grimsby and Cleethorpes Model Engineering Society. First is a 1:24 scale Watt’s ‘Lap’ engine, built by James Watt to power lapping machines at the Soho Works in Birmingham  in 1795, work previously done by horses. The original is now in the Science Museum. Second is a ‘rotative’ atmospheric engine typical of an engine to produce rotative power rather than pushing, say, pump rods. Finally an unusual geared atmospheric engine.
