Those are some interesting blueing marks on the exhausts. I wonder if the PO had attemped to de-carbonise the mufflers with the old oxy-acetylene trick - fire the torch in the muffler, get the carbon burning then whack up the oxygen to burn the carbon out. It's an old two-stroke trick that works, but makes the pipes look like that.
