Identify and Appraise

[chapoguzman]

Hello,

I recently cleaned out a relatives garage who was a hoarder. As part of the deal, we were allowed to keep any kind of scrap metal we might find. I didn't find much, just what looks like some type of ventilation system that may or may not work.

I have some photos attached, I was hoping someone could tell me what it is definitively as well as tell me if its worth my time to take to the scrap yard, or would they even scrap it?

Thanks,
