Hi, I am in the process of restoring a 6/70 car.  I am curious if anyone remembers what color the factory horns were.  The car was factory white but it was rattle canned white later in life. That is why the overspray in the first pic.  It looks to me as if it was painted black at the same time as the radiator support.  But when I tore it apart, the insides looked like an olive color zinc plating of some kind.  See the second photo at about the 4 o'clock position behind the gasket. Any ideas
