Lack of entries means that there are no sources describing Russian platers

Silver-plated tray. On copper. I am asking for the identification of the producer and the time of its creation
The tray is big and heavy 77cm x 53cm and 4200g
I will be grateful for your answer

What period is it from?
Is this Poznań?
Thx

Now I think I saw the signatures on the inside

Is it possible to determine the age of the item by these signs

Does anyone know these signatures
in what period were they created

Thx

Thank you very much for information and your time
