For Richard Reynolds & Co. Portable colliery winding engine of very unusual construction. Reynolds & Co. bought two of these engines, and according to the List of Engines made at Soho, the cylinders were 10½ inches in diameter. Dickinson & Jenkins identified this as the earliest reference to a throttle valve. Richard Reynold's son William was closely involved with these engines, and the firm became William Reynolds & Co. circa 1789 [?]. John Southern's List of Books describe the engines as being for William Reynolds & Co.
