How cool, I love it when I stumble upon old 'things' left out in the wilderness and undergrowth. Usually, in the UK, it's old buildings, caverns or mines we tend to come across. I do remember @rodp dragging me up a mountain somewhere in Wales when I was a child to find a WW2 Lancaster bomber engine (Rolls Royce Merlin), it was hammering down with rain, I was cold, wet and tired but still he insisted on getting to those coordinates! We never found it unfortunately, it must have been recovered or moved to a local museum before we heard of its whereabouts. Would have been awesome to see though.
