Winfield B polished alum intake, matched with Model SR-B downdraft Winfield carburetor. Intake is perfect for an original antique Winfield part..no flaws and polished. Carburetor ran when last on B engine. It is complete in every way and has an even patina that does not have to be changed to improve looks ! ALL parts of this setup are matched B Winfield parts ! The manifold is B. Check out the pictures. I would not hesitate to put this back onto my B engine and expect it to run well again. Even B choke and horn are present ! However , it is a used setup that you are buying. Plus shipping cost. SOLD PENDING PAYMENT...GOING TO PENNA !!
