Hi BufOn -
maybe next time you would like to use the Macro mode of your camera to get a decent photo of the marks - otherwise it is more guessing than knowing!
The design of your cigarette case is called the "bark" pattern, a more simple form of a trompe l´oile.
My guess:
Moscow town mark (in use 1882-1898)
master: Bekman, Andrej Wilgelm (the Russian writing of Wilhelm) 1860-1884
silvercontent: 84 Zolotniki = 875/1000
