Federal Signal Twinsonic Model 12F Series A1

And here we go again, I found this guy during my latest little lightbar hunting adventure. Another Early 12F Series A1 from a Wrecker, the domes on this were outright trashed. Very dirty but does spin up. Unfortunately my camera died during filming so it does end on a cliffhanger...

I will have more of this bar once I start tearing into it.
