Two Sterling Serving Spoons Elaborate Design

*These sterling spoons are 8.25" long x 1" wide at the bottom of the handle. There is a mark between the word STERLING that has a box around it, and pat. 1883. The mark has a lions head facing right, tail, legs all within a scroll-like square. See photos for best description. The last photo to the right shows the back of the handle.

I'm looking for the pattern name and maker. If you know kindly let me know. Thanks for looking.
