Antique silk lined silver jewel box h/m Birmingham 1921

An 100 year old round silver trinket box with a blue silk lining in the base.  The lining is in good condition.  Fully hallmarked for Birmingham 1921 on the side of the lid and the base.  There are a couple of dimples on the side of the base and the lid has been pushed down on the top.  Despite these marks which are commensurate with its age, it is still a very charming and usable box.
