According to what I found on the Old Chevy Manual Project web page that hood orniment is an older orniment. The 51 car orinment is a styleized Impala. The 51 to 53 54? orniment is similar, but is flattened, and squared off. That orniment maybe a car orniment, but it sticks in my mind as a prior year truck orniment. Someone with better resources, can feel free to correct my observations.
