My farmer cousin found this heavy metal device behind my late uncle's farmhouse (north Nebraska US). We first thought it was a pulley mounted on it's side, but there is no central pivot point. It is bolted on three points of the round (22in/55cm) piece. The only markings are the "19" on each leg. It was thought there was an icehouse in this area, gone before either of us we born (50+ years).
ANY ideas??
