The approximate location of this stone (as determined by hunting on google earth) is 15°26'53.38"S, 28°19'44.53"E.
It is a little way east of Libala Secondary School (which was looking quite decent from the outside). Nobody I spoke to had any idea whose grave this is. Does anyone know? The first row seems to include the letters OM and the digits .7.45. The second row has the letters (R?) M (IN?) and the number 18.
