The manifold is part of two sets of Hemi exhaust manifolds that I bought from the family of Floyd "Pappy" Cline who owned the red 4 door Hemi Coronet in Wichita, Kansas. The Coronet was parked in the driveway without the engine or transmission, and I made several attempts to buy it... but we couldn't agree on a price. The two pair of Hemi exhaust manifolds were priced to sell though... $150 bought both pair! I believe that one of the sets that I bought from the Cline family in the mid 1980s was the original set from the red 4 Dr Hemi Coronet.
