This Federal fire truck siren is a 12 volt siren has a brass face plate with a few small dents but still looks good. I attached a battery charger to it and it works fine really loud it was not grounded very well and the first time I tried it I had to spin the blower with a small screwdriver but then worked fine. Could probably use a good cleaning and oiling. Being sold as is and no returns. Any questions please ask.
