it was heat treated to stop the salt corroding it to a pile of rust and was painted in epoxy paint and given to the coast guard.
It ended up at hill sixty in Port Kembla. It came from one of two wrecks that sunk in the area. These wrecks are to be found in about 100 feet of water in the left of the bottom photo. I can not think of the names of the ships and this is from the earlier wreck.The other wreck might have been the Bombo which came to grief in the early 1900's.The first wreck was in the late1800's or early 1900's I know it had a girls name something like Jane or Alice but I'm guessing.
