Vasily Ashmarin for some reason (died?) he left the business until 1901. His brands "VMA" in the 20th century or not, or they are very rare.
I met information about Stepan Ashmarin in 1907, 1908, but perhaps he was only the head of his mother's factory. I think that after 1910 or a little later, the factory stopped working.

Soooo.....Gentlemen best guess at the original smith? Taking into account style and execution of set.

I have met many products where the brands "СА" and "Курлюков" are together. These are simple things: knives, forks, spoons. There were no enamels. It is difficult to talk about the pronounced style of "СA". It takes time and desire to determine the name of the master "СА".
