Donated by Naval retiree, Commodore Brinkhead of Bangor, who picked it out of a crevice near the summit of Glyder Fawr in Snodownia in 2011. In his note to the museum Brinkhead stated "I'd taken a long walk, as I was trying to fathom the "Bruiser" - a notoriously fiendish knot required in the raising of a 18th century gibbet-gauge. It was such an unexpected object to find at that altitude, that I sent it on to you in the hope that you could shed some light on its origins." The museum sent it for DNA testing in 2012, with the initial assumption that it is a fragment of shell, but the test results identified it as human. On loan from the Pebble Museum collection.
