I have a spoon with the marks as shown. The spoon is approximately 9 inches long.
What looks like a kokoshnik mark seems to purport to have the assayer as Anatoli Apollonovich Artsybashev working out of Vilnius. Please correct me if I am mistaken!
I think the maker is marked MG yet I have been unable to find this mark elsewhere.
If anyone has any information on this maker it would be greatly appreciated. I also understand there is a world of fake Russian silver. Your doubts are also appreciated!
