You are bidding on a Ford Deluxe horn button from about 1940.  It is made of bakelite, and has been painted silver.  It shows some wear, and is slightly misshapen from heat.  The metal back is in fine condition.  It measures roughly 2 1/2 inches in diameter.  It should be useful for a restoration.  Shipping weight is 7 ounces.  Please see my other auctions for vintage radio and audio items and tubes.
