If you needed some assistance in Mindanao just reach me out, maybe I can help you out on some things your not familiar with. If this is yamashita, well I very much eqiupt with knowledge and some gadgets too. if your near my location I can definitely help you out..As someone who frequents the internet, I am not lost on the bulls*** scale when a new account posts something like this. So I do really appreciate those that have taken the time to post.
Between some comments here, looking online and the fact I have reached out to some attorneys I am confident enough to head over there myself and start to do things like test, identify marks etc.
Something of concern, asking more questions, there are apparently other relatives from the same side who have been taking metal detecting equipment into what they refer to as "Japanese caves" which they admit they travel into government land. I guess that is my only remaining doubt, what is the best answer when being asked where and how these were found.
