I am looking for some help in identifying this what I believe to be Russian Tea Service. Let me start off by saying that the leaves, etc look to be applied in copper but I am sure that the main body is silver and not just silver plate. I hope that's ok to post here since it does say no silverplate but as I said, the main body looks to be silver and not plate...
I've done a fair bit of research but not knowing anything about Russian Silver this is what I believe I have based on the marks. Of course it could be fake but I will start from the top and see what you think;
Assay Mark: It appears to be A.T./1840 (A.T. in Cyrillic) and from what I've found could be Dimitry Ilyich Tverskoi since he worked in St. Petersburg from 1834 - 1851.
Makers Mark: N & P which I think or hope is for Nichols & Plinke.
Another Mark: CT which again I am hoping could be Johann Tegelsten.
Silver content: 88 Silver Fineness.
I'm attaching a lot of pictures with as much detail as I can but it does look to be a very fine service regardless. There appears to be the remnants of a gold wash on the interior too.
Any help you can give would be greatly appreciated. Thanks to all in advance.
