Good day!
Who knows, that could mean a brand on the silver speaker /1864 84 emblem of Moscow (George on horseback) and master ISE.

Interested in what the master or workshop ISE?

I.S.G. - Gubkin Ivan S. , a merchant and manufacturer . Established a factory silverware in 1841 . In 1861 g.bylo 88 workers, annual turnover of 500 000. AVAILABLE : cutlery , tea utensils , dishes, bowls of fruit, with black buckets , mugs with carvings.

Thank you.
About Gubkin found.
But here's initials ISE.
The last "E" and not "T".
Can you say something?
Photo attached.

Laid out by a fragment of your salary is difficult to judge the quality of work.
But it seems that this is not Gubkin.
Although he made a lot of salaries.

Well then - unknown master .....
For in reference I.S.E.
does not appear.

Unknown masters more than the known.
Hallmarks are real, and can be seen in these photos.
Apparently one in the aureole, other salaried.
