Vintage Sterling Silver, Onyx inlay bangle, hinge bracelet!

Got this beauty from an estate! Marked 925 and a makers mark that I can't quite make out. Bracelet measures about 2.75" across and looks like it would fit a size 7-7.5" wrist. Onyx inlay measuring about 6x11mm, and unclasps from the front (by the onyx). Please inspect and enlarge the pictures to assess the condition of the item for yourself.
