Interesting. Is your hood a 2 piece with a hinge, or a 2 piece welded together? All of the 46-48 Plymouths I've seen had a 2 piece hood that was welded (factory) at the seem. The seam was covered with a metal strip down the center, usually chromed. There were gaps in the weld for attaching the strip from under the hood.

The book I have mentions an "alligator style opening hood" under the improvements for the Deluxe body line in 41. The cheap car does not list the "alligator" hood opening, and its not clear if it was an across the board change. It does not list any hood style opening again after that mention in the 41 Deluxe section. Gene
