Thanks Qrt.S for your answear .
I took a photo of the podstakannik after coming home, before cleaning it. Today I will polish it :)
My English is weak, so maybe you sometimes misunderstand me. Of course, I know that Takkinen is from St. Petersburg and it can not be him, I meant that in Postnikova Loseva M.T. it's only Takkinen.
I've also took a new photos that I can see better. Do you think that there are no dots does not exclude Mihail Jakolevich Tarasov? Hmm?
Thank you, maybe someone will find something else.
Click on the photo for better qualitty.
