Original 1956-59 Mercury Dealer Master Chassis & Body Parts Catalog [dated Revised October 1961]. This Parts Book covers the Full Line of Mercury Models for these years. This is what the Dealer used to order available Factory Replacement Parts to Repair your Car. It has Part Numbers, Description, Application, Quantity and Illustrations. It is in good condition for its age showing some wear, soiling and blemishing from use in a Dealership [see photos]. Spine has been taped. Very rare and informative piece for the Mercury Owner or Collector.
