Yes, I have seen the Map! I believe it to be true. Also, It is one of many found in a violin case in a house the Japanese once Occupied . Japanese came to home asking to retrieve unknown item. Filipino wold not let until the befriended each other. Maps have stayed in Pinoy hands since discovery.
Contact Kaloy via cell and have a chat with him.
