View of an engineer testing control valve for water mains at Rolls-Royce Engine Test factory. The factory produced Packard Rolls-Royce Merlin XX engines. Label on back: "Deep under the foundations of the Rolls-Royce Engine Test factory, an engineer tries out a control valve handling the water mains that feed the cooling units on the testing engines. Water sufficient to handle the needs of a city of 50,000 population is required to cool each day's quota of engines as they come from main assembly to the dynamometer test blocks."
