Kevin, I confer with John, once saw the aftermath of a steel 100 that had been breathed out. Very ugly inside. Don't know the scenario behind it, the problem was between the ears and not the equipment though !!! Also saw the aftermath of an alloy 20 which had been breathed out, not checked and stored full of salt water, the scrap metal dealer now owns a 20 with FAIL stamped around the neck.
