Vintage Acme Thunderer whistle that is is excellent, LOUD working order. It has a ring, so it can be worn on a chain, or attached to a key ring. There is some surface wear to the silver tone finish. It measures just under 2 inches long.
I currently have several pieces of vintage advertising in my shop, including other whistles, and am happy to combine shipping. To see them all, type the word, "advertising", or, "whistle", in the California Girls search box at the top of this page
If you are ordering more than 1 item from my shop, wait to pay until I send back an invoice with the combined shipping discount.
