The Set

I had promised in "Chess and Gefilte Fish" to load pictures of the chess set discussed there as soon as possible. Well, the owner of the set had kindly sent me pictures of the chess set. It is a beautiful, obviously Russian-style set, from early in the 20th century. It was made in Russia or the USSR (the set has cyrillic markings) but there is no exact date. Can any reader solve the mystery of the set's maker?
