Hi nnerka1 -
This is a very nice, early niello snuff box. Congratulations! If you own it, please clean it with soap/water and a soft tooth brush to remove the residue of an old cleaning agent (the white stuff!). The condition is excellent!
The maker is a well known niello maker (objects from him are in 2 major Russian museums exhibited) but unfortunately not by name!
