This is a reguilt carburetor that has sat on a shelf for over 75 years. The Packard part number is 418899. The Carter number is WGD 728-s. This fits 1949-50 Packard junior series 2301 cars. This carb will need a through cleaning and probably a new kit installed as it is dusty and dirty from shelf ware. See my other listings for more Studebaker-Packard parts.   WPS
