Lionel Century Club Pennsylvania GG-1 18314 test sample. Unusual in that one side is completely unstriped and without Keystone. Nose stripes not applied all the way around. Notations written on silver pen on the top of the locomotive. Unpainted pilots and frame. Really neat example of this locomotive.
