    SC-686 75k Photo shows Okinawa in the center with Buckner bay to the right and the island it was shipwrecked on (the information from Vernie George Runnion says the name of the island is Tsuken Jima-not Kudaka Shima, uncertain which is correct. On investigation both Kudaka and Tsuken are around that bay, so it is very possible that there is confusion)
