Hi Juke -
In Russia were several Ovtschinnikovs - not all were famous or Court Supplier!
This maker made umong other things, "Serebrjanaja rjumka" - something like a shotglass - these were never very artful - just for dayly use.
I always try to substantiate my statements with photos from my extensive collection or excerpts from specialist books. You have to look and read!
Basic knowledge of Russian culture, Russian silver and the Russian language are simply necessary in a forum for Russian silver to have a say.
It is not fun to explain each post several times - until the last one understands it!
