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.

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.

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.
