For Sir John W. Lubbock Bart. & Co. The boat ran between Cadiz in Spain and Port St. Mary and was called Relampago, although it was initially referred to as "Hercules No. 2", and also appears to have sometimes been referred to as the Lightning. The engines are listed under "Lubbock" in the Drawing Office Index.
