Philips Wood & Lee (formerly Salford Twist Co.). Cotton mill, Salford. This engine was made from an alteration of the firm's two 30 horse power engines and a new 48 inch cylinder. George Lee was closely involved in planning the alterations. The firm appear to have referred to this engine as "Pluto". A 10 horse independent engine was later erected alongside "Pluto" [see Portfolio 5/844b]. This engine was omitted from the Catalogue of Old Engines.
