Hi,
Forgot to add.
if you could give a close up of the dome of the guard i'll be able to help you with the remaining two figures as well.
The KirtiMukha can be seen even used till date adorning the elite doorways of temples and arches behind the idols of gods and goddesses...!!!!!!!!
Also let me know if you need details of the incarnations and the stories behind them
I'll suggest a Maratha origin for this piece. (Tanjore to be specific)
regards,
Bhushan
