Gorgeous Art Nouveau Antique Ornate Sash? Belt Buckle Repousse Victorian Lady - Goddess Harp Silver/Brass

This is a gorgeous very old buckle, I believe that it is a sash buckle because it does not have the normal buckle backing, please see photos there are two bars for the sash to fit through. This is brass under the silver and is showing somewhere on the front please see photos. This could be easily re-washed if desired. Please see photos for approximate size and further information.
