mendak inscription

[A. G. Maisey]

Turn it upside down I can maybe get a cursive "dha" out of it, + something else.

The"o" ? No idea at all.

Normally these inscriptions are for protective purposes.

Its not a calendar number that we look for, its a Candra Sangkala number, each number of which represents some different things, which thing applies in a certain situation is something else again.
