Family heirloom

Maybe someone will see this and can help me. I am researching our family and trying to piece some bits of information together. I wish I had been more intentional in asking momma more about our ancestry before she died. I believe this may have belonged to her step-grandfather - Maybe William Rogers McConnico. I know that the owner of the pin was the chief of the volunteer fire department and when he retired they gave him a lovely silver water pitcher that I now have in my family collection along with this pin. I have no idea from which city or state it may have come. Perhaps Arkansas or Mississippi, but I am really not sure at all. I believe the manufacturer was T Hausman. I have researched the trademark and they were jewelers in New Orleans in the early 1900s. I would love to solve the mystery!
