Vintage 23 Inch Truck Air Horn Grover Products Los Angeles Pat. Pending 2281g39

Vintage truck air horn. Found this in my garage when I moved in. Measures 24 inches long. Patent pending . Grover Products Company. Los Angeles. In good shape for its age. Some pitting where horn will be attached. Otherwise horn shines nicely. Was unable to test as I have no idea how to do this. Hang it in your garage or put on your truck. Thanks for your consideration. If you are in Hawaii , Alaska or out of country please let me know as shipping will be a bit more. Thank you so much.
