I bought a '53 3100 a couple of years ago. The whole truck was painted light blue inside and out. I recently took the non fresh air heater out and took it apart. Where there is no blue paint it is kind of a hammered finish dark green color. I thought the heaters were a kind of bronze or tan color? It has a chevrolet emblem on it? I thought maybe it was a GMC? I don't know. I was just wondering because I'm about to rebuild it and wanted to paint it the right color. Thanks.
