Hi LS,
Wow! thanks alot for the info n pics.
We're planning to have the area scanned/detected by Jan 2012.
I will update and share my experience here once done.
BTW, this shell was found cemented to the ground and not inside the hole.
The location is approx 40 meters to shore in an inland jungle somewhere in Tawi-tawi.
Also a Jap straggler was last seen on that area on 1946.
Thanks again LS!
