Spasibr you very much! And do not advise, how do you know about the authenticity or get an expert opinion? Where to go and how to know the approximate value of the subject??

And why Moscow trial?
Do not shop Ryukkerta in St. Petersburg was?

 
Ryukkert worked for the Moscow branch of the company in 1887 - 1917 years.

Indeed, the workshop Ryukkerta was in St. Petersburg,
hence the objects they made there and make their way.
 Where they are - another question.
 IMHO - this is a remake.

I will not try to say, photographs, remake or not.
But the issue is much broader and deeper than many think.
Who cares in general for Fedor Ryukkerta:

and for the hallmarks here (also in general):

In recent years, the life of FI Ryukkert lived in Moscow for Vorontsovskaya street 23, in Moscow as he died, was buried at the cemetery.

I beg your pardon, but the woman's head looks not right, and left?
Then, this is another period
