A very unusual shape solid silver vesta case,  ribbed design back and front, fully hallmarked  BIRMINGHAM 1897 makers C&S ?
2 inches long ,  fancy engraved initials on the top HR 
Good antique condition no dents, strong hinge snaps shut but not  quite fully and signs of stress near the hinge, (see pictures) i am sure this could be sorted out. 
The  oval shape and design is very appealing .
