The Carter 478S WD-O WDO carburetor is a vintage automotive component, specifically designed for use with 1941 Packard vehicles. This carburetor is a testament to the engineering prowess of the past, combining functionality, durability, and style in a single package.
The Carter 478S WD-O WDO carburetor is a double-barrel carburetor, which means it has two barrels connected to a single throttle shaft.

From my research it looks like the basic WD-O was used on various make cars from between 1935 and 1950. It has automatic choke actuated by engine heat. Its OE/OEM part number and manufacturer are both 478S. Apparently Carter built the basic WD-O carb, and made minor changes depending on what car manufacturer it was being shipped.
This came off a 1939 Packard 120, straight 8, Flathead engine. After I researched it, found it was not the correct carb for 1939 model, which instead used a Stromboli, so located and installed carb, no longer need this one.
