Reed and Barton serving piece

I need help in identifying a piece of silver, very unusual and just magnificient, purchased on ebay recently and just love this item.

The ebay listing is 140199273005, if you go to ebay and put the number in search it should still come up. Many pictures on the listing and you can supersize them also.

Very unusual and interesting item, I would love to know more about it, I myself think this is a rare item, I have no clue but I hope there is an individual out there that can help me.

Thanks so much in advance.

Best regards,

Shirley.
