I found this in the middle of an old trail in the woods. It has an outside layer of non-magnetic metal, maybe copper.
Then another slightly thicker layer of non-magnetic metal, maybe copper again.
Then what I believe was once solid wood, though it looks like it is just lined with wood.
Any idea of what it is?
