MarkAt first glance, I wanted to say it's a reproduction piece. We had a previous thread months ago about fake Napkin Rings, made to look like early 20th Century pieces. These were prevalent on ebay about a year ago. The item pictured below is one of these reproductions...
But after a closer look, I think yours has far greater detail and superior workmanship. I believe that the reproduction piece was modeled after yours, which appears original. I suppose this doesn't help to answer your question regarding the original trophy, but somebody apparently thought enough of it to copy it!
