My guess here is first I'm almost certain it is Silverplate. I think the orgin is Middle Easter, Arabic, Iran, and Etc. Base on the stamp and the overall Pattern. I did look though my books earlier and came up short. My guess is also the age of the pot is Post 40's, or after the great Silverplate era, These items was mostly made for Holiday and Export. I think it is a very Unique item for sure, and would most likey be kinda of a rare item overall.
