Cornish Pumping Engine built by Harvey & Co of Hayle, Cornwall, for display at the International Exhibition of 1862

This superbly constructed engine - it might be termed a model, but it is in reality simply a small version of what was ordinarily a much larger machine - was built by one of the foremost British engine-builders, Harvey & Co of Hayle. Harvey's acquired a formidable reputation providing engines to pump water in Cornish mines, for water supply, and drainage purposes, around the world, which made the company well known and attractive to many engineers eager to make their name.
