My final rendition of the horns, I might redo the chopper but for now this is my final reasonable remake! The American Signal Corporation T-128 siren was a 128 decibel air raid siren originally developed by EAS (Excel Alerting Systems) Who's president branched away from Hormann/ASC soon, the ASC people saw this 'brillant' design and decided to shake some hands and sign some papers exchanged between ASC & EAS and boom! ASC Tempest-128! This model has reodne horns and thats about it as the rest is pretty good to me.
