Hi Ian,
silver pill box
Marked Holland and below three pseudo/fake or fantasy marks; pseudo year letter, pseudo town mark for Rotterdam and crown, pseudo maker's mark.
The maker's mark could be in the red circle but perhaps it's the sword mark used on small works minimum 833/000 fineness.
Please check the box for a proper maker's mark.
Information about sword mark and year letters see;
