When I first pulled this out of the ground at the base of a 200 year old oak tree, I thought it was a wheel. After cleaning and further inspection I am positive it's not a wheel. Inside is a type of butterfly valve which, when manipulated, opens and compresses what seems to be some type of bellow. The entire piece is brass except for the bellow which I think is copper. Any ideas??
