Empire by Shreve or Durgin

The sterling world is full of "Empire" patterns. There is Whiting's Empire (1892) pattern. There is also Durgin's Empire (1895) pattern. And, Empire by Towle (1894). I also found references to Empire patterns by Reed and Barton, Mount Vernon, Ercuis, as well as Buccellati but could find no examples. However when I went to look at  Empire by Shreve I found it was the same pattern as Empire by Durgin. 

So if this looks familiar and you know Durgin's pattern, that would be the reason.
