This is an original 1948-53 era Dodge Truck 6 cyl Intake / Exhaust Manifolds.  Good looking condition, didn't find any cracks, but has some pitting in areas-see photos.  Heat flapper is not stuck, but does have some wear and a few broken bolts that hold the intake manifold on-see photos.  This came off of a '50 era Dodge truck.  Not sure of exact years or models this may fit.  Please check my other auctions.
