Went to look at this yesterday to buy but decided it wasn't worth what he was asking so I told him there wasn't much I could do with it.
He paused and said "My wife wants it gone from the yard... If I gave it to you would you haul it off?"
He even did most of the moving and lifting it on the trailer.
The firebox and frame beneath it is in pretty rough/rusty shape. The rest of it might be OK.
