In pic 62 the long curved piece is from a tillage implement, in some places called a subsoiler. In Pic 51 is a galvanized can in the center, that is a corn planter box, on the lid is IHC, a collectible. In 52, the big hooks, were attached to a rope, and dropped from the barn haymow down to a wagon of hay, to be hoisted inside, those are big ones. 65, the red pipes with the curve, look like gate closer/locks, great when one has livestock.
