This is from the book mentioned above:
The mark is not shown but described as ‚‚MS‚‚ in Latin.
One of the artists-sculptors who brought new plastic principles to the silver production of Carl Faberge was M. Sokolovsky. His name is mentioned in a number of documents from the handwritten, printed and graphic collections department of the Moscow Kremlin Museums.
Judging by the name and surname, Marian Napoleon Sokolovsky was a Pole by birth, possibly a descendant of an ancient Polish family (Sokolowski). Obviously, the Latin letters "MS" were used in the mark in connection with its national identity. In the addressbook of the calendar "All Moscow", he appears as the owner of the art-silver workshop, living in Glinisti lane, 6. Production was located on Pereslavskaya street, 45, and was mentioned in the "Gold and silver products" of the same directory until 1917 .
