What is it?

[Alenka]

Please help or show you WHAT IS IT? "This thing has been found an heir. My father was sredninkim collector. Unfortunately, the heirs did not pull his father took over the arts. This thing is found when disassembling the galleries after the death of his father. What is it? What period? And of course the approximate cost? Thing is not in my location now, but if this is something truly different and need more detailed photos, after the New Year will try to do. Now it would be interesting to know in principle that it is and what they eat! Thank you very much. I hope very much for your help.
