The scheme has been in operation for some months for the Gipsy Queen Series 70 engine, but the new service willnow embrace all of the Gipsy Major 1 series and the later ver- sions of the Gipsy 6, now known as the Gipsy Queen 2 and 3.The de Havilland Engine Service Department will merely require to know when an engine of those types is approachingthe time for a complete overhaul in order to arrange for an overhauled engine of the same mark to be ready as immediatereplacement. Replacement engines will have been overhauled by Gipsy engine specialists, and will incorporate all the essen-tial modifications up to the date of installation. Each engine will carry the same warranty as given by the company asmanufacturers with each new engine, providing free service and free replacement if necessary, during that period. Opera-tors will be able to assess accurately their annual costs, which will not be dependent upon charges for specific replacementswhich become apparent only in the event of overhaul. The scheme is unique in accepting old engines at a fixed price,regardless of condition, and providing a reconditioned engine with guarantee. Charges are as follows: Gipsy Major 1, ^1Gipsy Queen 2, £225; Queen 3, £225; and Queen 70, £600.
