My possibly final rendition of the Federal Signal thunderbolt 1000T Dual Tone Air raid siren. The original Siren that I made sourced old parts and small refurbishments but needed a almost full remake as the wires were made from a bumped PNG and the motor was old. I also redid the 1003 and can possibly do B series thunderbolts and C series Blowers! I also remade my Blower, mainly the motor though and now the thunderbolt looks better and is way more detailed even sporting a completely redone rotator, chopper, wiring and chopper cap! However, I resourced my ChopperCap serial number because that has become the staple that the thunderbolt is mine.
