Oil tank
Original oil tank has been inspected and carefully disassembled in section so as to preserve the shape as well as to salvage as many components as possible.
The outer skin/surface of the tank has a number of large dents and corrosion/pitting.
Once the tank was carefully cut open it was found the inside was in a lot better shape and the filler neck and oil return tube seems to be salvageable at this point, closer inspection.
Dent removal and rework will be needed once the remaining section of the oil tank is deconstructed.
