Generally
A factory-new Vacuum contact, Masterswitch that controls the Air Condition, is mounted on the torpedo wall. It is in an original box, is in perfect condition and has never been fitted to any car. A spare part that we call NOS It stands for New Old Stock, i.e. spare parts that were manufactured when the car was new and that were just sitting on the shelf. So not newly manufactured parts, hence New Old. The Cadillac part number on it is 7302385
