I will share more details tomarrow on the RRC inscriptions ( which according to the info is on the westren wall) and some photographs i could manage- as i was not allowed to take. This temple is maintained by state emdowment board. The walls inside and out side (including the inscriptions are covered with thick white wash. (-sunnambu) All epigraphs are covered with thick coatings.
This temple is not under TTD. It is maintained by state endowment board.Renovation is going on and they are planning to sand blast the walls according to the Gurukkal of the temple.
Our members have to suggest, whether sand blasting is OK? or should it be taken up with the Government of AP.
I will try to give more info on this once i complete my tirumala visit tomarrow. I will try to get the TTD publication on inscriptions tomarrow and share with you.
