Im making lots of Final air raid siren models, here is the Alerting communicators of America (ACA) Hurricane 130. This siren reaches 130 decibels when supercharged and utilizes a vertical blower which was splashed lubricated (I think) and had crazy issues with the blower simply because it was vertical and not horizontal (I think again). This is just a recreation of the horn and rotator, the rotator is completely redone including everything inside of it. I might remake the chopper next but honestly, this is looking good so far!
