Hi ElicottCity -
Khlebnikov, Ivan Petrowitsch, 1867-1871 was one of the most famous Russian silversmiths and enamel artists. The firm went later to Moscow and was known for their outstanding quality and design.
Now the bitter part:
the shown mark of Khlebnikov is the mark used in St. Petersburg, between
И and
X was a dot, later without dot.! Your mark is a fake.Townmark Delta on Kokoshnik is for Moscow. Your townmark is wrong, the Kokoshnik is the later one - wrong.
Quality: Khlebnikov was known for his elegant designs and his sophisticated enamel colours. The colours on your napkin ring are vulgar, the design is crude. For a napkin ring about 150 years old the overall condition is brand new,(enamel is due to use,environmental influences, etc. ageing and get some typical patina, the enamel is damaged slightly through tear and wear, the twisted wires of the cloisonné technic are no real twisted wires but galvano plastic made.
Facit: Typical fake seen often on online auctins, auction house etc.
Here the mark (with dot, but also without dot possible):
Original mark with correct Kokoshnik:
Original design and enamel colours:
