Here is a vintage stainless steel whistle, it is heavy duty. Stamped police special. Jump ring is attached. Cork ball inside. Plenty of scratches, lightly tarnished, small dings, and dents. 1 3/4 inches long Buy from a trusted and reliable seller. I source my items from estate sales, auctions, thrift shops, and yard sales. My home is pet friendly and non-smoking, but I cannot vouch for their original homes.
