I have a 12 cylinder Seagrave engine that was installed in a 1933 Pierce-Arrow coupe. However, the orginal carburetors and air filter were removed and a new carburetor was installed with a new air filter. I would like to go back to the original carburetors and air breather on the Seagrave engine. This requires the carburetors, air breather and linkage. I have been told the Seagrave engine was made by Pierce-Arrow and is identical to the V 12 installed in the Pierce-Arrow automobile.
