When Ford brought out the 9N in 1939, the stamping dies for the hood wasn't available yet. So, the first 600 to 700 9Ns had a cast aluminum hood, but they were painted gray in the factory. The rarity of the aluminum hoods, were were prone to crack, current owners have polished the aluminum to a bright shine and leave them unpainted. The video below (not mine) shows one of these polished aluminum 9Ns.
