A redone version of my American singal corperation Tempest 135 air raid siren. So apparently I saw this photo from a video of someone's t135 in a backyard and the entier 'flower' or horn arangement is cut in half for this futuristic metal 'block' that takes all 8 horns and routes them directly to the chopper compared to the t-128 This siren is capable of 133.5 decibels at 100 feet and is the older brother to the ASC T1128
