Your image apparently is a Tibetan style depiction of the Bodhisattva (Mortal Buddha) of Infinite Light, Amitabha or Amitayus. The Ming Yongle Emperor (1403-1424) commissioned a number of famous ones in same form during his reign, and Qing emperors participated in the same acts of faith.
The character on the back of this one is 位 (wei), meaning "seat" or "position", which might be construed as "throne" in this context. It is not a Chinese surname.
Acetone might be usable to remove paint without affecting patina, presuming the black on this image is patina and not the residue of lacquer used as a base for past application of gilt. You could test a spot on the back to determine whether using acetone causes such harm. Maybe others have better ideas in this regard.
