A great police tool. Our uniform pants had a small outside pocket located at the rear of your right thigh to carry it. Mine was a little longer, but looked the same. Used it as a door knocker and defensive purposes of course. As stated by others, it was removed by the civilian powers to be. I still have mine (in the truck) that was issued 44 years ago. I can't say the same for my issued duty revolver and wooden night stick. I'm glad you shared the photo.
