I am hoping someone can help me with two things:
1) Is this maker's/assay mark legitimate? Is there a possibility that it's a forgery?
2) The maker's mark appears to be cyrillic "BA", which according to the 925-1000.com resources could be Vasily Agafonov, V. Akimov, Vasily Andreev or Vasily Alexandrov. The assayer appears to be Lev Oleks.
The piece is a 10.5" silver oklad icon with areas of cloisonné.


Thanks in advance!
