Help with assayer's mark and maker

[InquiringOne]

I would appreciate help in identifying the mark and maker of a niello snuff box. As a first-time user of this forum I hope I'm following the correct format. I'm sorry that the image is so large.

First of all. One should always show photos of the whole object and not only its marks!
Nonetheless, the assayer (Latin NK) is Nikolay Nikolayevitsh Korbitsky working in Moscow 1886-1887. The maker (Latin IF) is Ivan Nikolayevitsh Futikin 1863-1897 as well in Moscow.

Show a picture of the object if you please, thank you.

Thank you so much for your response! Below are images of the cigarette case, which I mistakenly called a snuff box in my original post. I'm still having trouble shrinking some of the images.

[Qrt.S]

You are welcome. However, I forgot to tell you that there must be the same marks on both halves. if not, your are most likely dealing with a fake. The view on the box is from Moscow showing parts of Kreml.

Hi, Qrt.S

From where you have information? From the "P.-L. book"?
I have very strong doubt that the НК is Korbitsky Nikolay Nikolaevich.
Korbitsky appears for the first time after 1911 as a probirer of the Assay District of Kostroma. I don't think, that in nearly 30 years before this, he was a assayer in the "Second Capital" of the Russian Empire.

As we all know there is a lot of unclear matters regarding Russian silver marks. If it is not Korbitsky then who is it?

Thank you for the additional information about the importance of having both sections of an object stamped by the same marks. Since both sections of the cigarette case are stamped, I'm assuming this is not a copy or a fake.

I assume that it is Kulakov Nikolay Vasilyevich. In 1885 he is mentioned as the assistant to the head of the Moscow assay office. Subsequently he was the head of the Odessa assay office, of the Riga assay office and, at last, the head of the Petersburg Assay Office since 1895.

@Dad
OK, sounds reasonable, let him be Kulakov. Thanks for correcting me.
However, mind my asking but I have no notes of Kulakov being in Odessa. That must have assumable been happened apprx. 1888- 1892 because He was in Moscow 1886-1887 (?) and from 1892 to 1895 in Riga and then finally in St Petersburg 1895-1898.
Thank you in advance.

Yes. In 1888 Kulakov become the Head of Odessa Assay Office. In this time (1888) Sorokin become the Head of Riga Assay Office. In 1892 they change these places. One to the place of another. "Rotation". )))
