Thank you Goldstein for your response. I thought also that maker is Nikolaj Kemper but I really have some doubts if the maker is identified correctly. At first, it looks like A. Romanov was an assayer in Riga and Warsaw but not in St. Petersburg. But more important that Nikolaj Kemper's mark has no dot between initials. There also makers' marks of Nicholai Karasyen (1886-1899 Vladikavkas), Nicholai Kozin (1898 Kostroma), Nikanon Kosaryev (1898 Kostroma) and couple more marks of unknown makers from Kostroma, Jaroslavl and Astrakhan that are very similar to Nikolaj Kemper's mark but all they have no dot between initials. As you can see in my picture, there is clear dot between initials
