You are purchasing a lot of three hand-painted metal plates that are similar to automobile license plates. They obviously are not meant for cars. But they were obviously screwed on to something.
I have no idea what Huss and V S stand for. Here in Michigan, you don"t need a plate on the front of your vehicle. So these could have been on the front of a car/truck.
They measure 12 by 6 inches.
