The bearing sleeves were found in the "Carpenter's shop" of the old village, not at the suspected castaway campsite which is on the other end of the island. We wanted to excavate the carpenter's homesite thinking that various materials not put to immediate use would have ended up there. We were right that a lot of stuff ended up there, including the bearing sleeves, but unfortunately not much of it is consistent with AE's aircraft. We still don't know that the bearing sleeves are consistent with AE's aircraft, but apparently they were used in aircraft in general at least during WWII.
