Commercial canopy cab apparatus

Could this be orig. Dunkirk,MD., and then Bedington,WV?

I snapped this thing on it's way out of the house on a call, many years ago.  Note the slight blur to the photo.  I never saw it again.  I never got any into until later, when I ran into a guy who had run with them, but was then at another department.  He told me the capacities from memory.  I have no clue as to its origin, nor its current status.
