I can't remember if I posted these before.

Houstin Whitter and Gratiot Fire Station.
Siren being installed
I'm not sure what this one is, may be a first run Chrysler.
Building in the background is the now gone Hudsons Building.
So this siren is on the roof (truck in all) It may be ontop of the old City hall.
Also gone.
And this one was marked Detroit Fire department testing the siren.
Location unknown. But the siren may be running, since they are covering their ears.
