Modernist - Heavy Sterling Bangle Bracelet - Signed

This signed (JU or JH) bracelet is stamped with what looks to be 2 initials. If it is JH ...that means John Harding... a very high end designer!!! It is quite heavy and solid. IMO this could be worn by a man. It has an oval shape with an unusual shaped outside. I've included images of before and after polishing.
