Found this little guy in Midville Georgia, looks to be a small siren like a Model A but it almost appears to be rotating. However 2014 and 2016 views show no sign of movement, so could be defunct or not rotating. https://www.google.com/maps/@32.8181944,-82.234932,3a,15y,311.39h,103.34t/data=!3m6!1e1...
