Hi Ubaranda -
it is always difficult to judge blurry photos taken somewhere from the internet! If you own this cigarette case - please take some clear and sharp photos.
I am with Qrt.S - the shown mark belong neither to Nikolaev nor to Nikitin. Without better photos it is just speculation...
In my collection I have numerous cigarette cases of both - all the marks are clear and precise!
Have a look and pay attention to the different Д`s!
