I have excellent news for the Enthusiasts about the Gamewell Codewell (Cosgrave) siren in Jerome AZ unfortunately there are no recordings but there is some great news after a quick email with the police chief in Jerome AZ he said
"I am in the process of replacing a relay and radio interface. The siren is still functional and will be back on line shortly.
Allen L. Muma
Chief of Police, Jerome Police Department. "
so hopefully somebody can get a recording of it once it works
