Thank you for the suggestion of inquiring over at the H.A.M.B. The kind and knowledgeable folks over there determined the grille to be a combination of pieces. The horizontal bar is from a '51 Kaiser and the teeth are from a '55 DeSoto. They all said it was a nice piece. I'm grateful for all the good folks in the automotive hobby that are willing to share their knowledge. Thanks, Kevin
