I bought these tail gate parts at Hershey. As a package. But the one that I did not paint. I have never seen before. Can any identify this part. I'am not sure it is even a tail gate part.
Looks like that piece was the hitch where the linch pin was placed to tie the trailer to the hitch on the car. Before WWII trailer balls were not common, the blade and fork type hitches were typical.
