Built circa 1900 by Markham of Chesterfield and used by the company to drive a portable boring rig for reboring the cylinders of winding engines. The simple slide valve cylinder is 6" bore x 8" stroke. Note the two bar crosshead guide and pitchfork connecting rod. This is a very simple and robust little engine. There is a larger and more solid Markham vertical engine on display in the Chesterfield Museum.
