Unfortunately the marks are on only half visible. One thing is for sure. The town is not St Peterburg but Moscow. You can see St. George's head in the right mark. The double eagle mark to the left is more likely a part of a court supplier mark, but...? BC (Latin VS) is the assayer, and he could be Vladimir Smirnov, Viktor or Veniamin Savinsky, however, impossible to know which one from only a part of the mark.
Icons are very often faked and the way the hallmark is punched is dubious. In addition, there is no maker's mark visible. Have you investigated whether there are any other marks elsewhere on the object. Finally, I'm afraid I'm a bit suspicious....
