My dad ended up with this iron thing. Its about 18-19 inches long and 7-8 inches wide at its widest point. It was found on a farm about 60 years ago and the man that found it, the same guy that owned the farm, said he had no idea what it was. Round edge triangle describes its shape for one end of it. If you place it on the ground with the slit in the up position it looks like a boat hull. Anybody know what it is?
