A body parts

I'm interested in the rear blower. Tell me more about it. what did it come out of? is it complete?

It came out of my car when the old boy who owned it put in speakers.

the switch is still in my car, not sure about wiring harness..will not be to spring when I can find that out and the hose is gone. It is a 2 speed and it worked when I hooked it up to power.

oh, our car is a '75 duster.
