1960s Federal Thunderbolt 1000 Air Raid Siren #1

I'm uploading two Cold War-era Federal Thunderbolt 1000 Air Raid Sirens for your use. I discovered these files somewhere and converted them to STLs, leaving their details intact so you can modify or slice them as needed. These sirens were produced by Federal from the mid-50s through the 80s with only slight modifications, making them an authentic Civil Defense unit.
