Antique Egyptian Revival 19th century silver plate Samovar with hallmarks

I am looking to sell an antique Egyptian Revival 19th century silver plate Samovar which has been in storage for quite a while and blackened with age. This appears to be silver plated with lots of age tarnishing / blackening. Egyptian influenced finial to the lid and has a bulbous body as photographed plus hallmarks. Handles to each side and four ball feet. Little tap to the front looks like it is missing a part or two as photographed. The cartouche to the front is engraved with a coat of arms and motto which may require further research. Could be military related or possibly from a notable family name. I am sure when this was originally made it would have cost a fortune. I can see a few areas of silver plate wear exposing the base metal. I know these pieces can be replated, however I am just selling it as you see it, blackened and in need of polishing and restoration. Metal may have some light scoring or dings / dents too, but nothing of notable concern. 

A really nice and unusual piece that warrants further research due to the coat of arms and motto. Perhaps you are into Heraldry and can identify this, if so then I’d be happy to hear from you.  

Measures approx. 15 ½” in height with lid.

Weighs 2.3Kg unpacked. 

This is just basically being sold as you see it in the photos, the photos show the exact condition better than I can explain.

Please note that any international postage will be through eBay global shipping and I have no control over these costs, please note this prior to bidding.
