It look more like an one section per side longer AeroTwinSonic to me than an AeroDynic.
A model 24RVF in a longer housing for full sized vehicles, whatever it might have been called.
It seems it have individual motors, probably because of the length.
Maybe a special order by this fire truck manufacturer.

I asked him about other light bars and he said his brother runs a prop warehouse in Hollywood which might have some promising leads. I will keep my fingers crossed.
