I was wondering about the black bits, thought maybe he'd singed it by having the dull bar in one place for too long. If it's staining from metal fixings though, they were really deeply embedded.

metal could of only been 2-3 inches in to the tree and the staining from the metal will sweat through the timber over time, even only a couple of nails banged in to tree will show a staining after a few years and the longer its left the further the staining will travel.
