Identify This Mystery Object

The Mystery Object

I have something I want to put out for everyone to take a look at. My hope is that maybe someone might know what the heck it is. It was found in the woods near an old farmsite (I don't want to say exactly where just yet, on the off chance it might be rare), and I have no idea what it is. It seems to be made of copper, judging by the coloration and discoloration. If I remember correctly, it's roughly about two feet long, give or take.

The catch here is that it may or may not have anything to do with the farm in which it was found. It's not very far from the barn, but it's sitting in a small creekbed. It may or may not be connected to some copper tubing that is visible nearby. The tubing comes out of the creekbank and may come from the barn as some sort of drainage system. Since the object is in this small creek, that, to me, at least raises the possibility that it could have been washed there from somewhere else, and have nothing to do with the farm. It could be an old car part for all I know.

Does anyone have any idea what this might be? Here are a couple more pictures. If you have any ideas, feel free to speak up.
