My Great Uncle had a 1936 Chevy 2-ton,with a corn-sheller mounted on the chassis.Sheller was powered by a 4-cylinder,(maybe Hercules),engine. He got too ill to operate it,so it sat in his yard for years. It was retired about 1960. I'll have to contact some cousins,to find out what happened to it. It was in too-good condition to scrap??? time to dig...
