for the interested in children´s toys from Russia I recommend the following book or a visit in the State Historical Museum in Moscow!
By chance I found silver sugar tongs from a doll house. Measures in cm!
There were also in the size matching tea and coffee pots, etc. made in silver. See photo.
Here the details of the sugar tongs made by Silventoinen , Pekka (PJS) from St. Petersburg:
