DMP whistle

"This belonged to my gt grandfather Henry William Hanlon who was in the DMP. He died in 1920 at the age of 53. This really has been a treasure to me ever since my father gave it to me when I was a child. I grew up in England longing to visit Ireland and my goodness to be able to hold in my hands something that was, in a way, SO personal to my great Grandfather was always a HUGE thrill. "
