Hi John,
French import mark for silver called the Weevil. Silver items from French treaty countries were struck with the weevil in a rectangle mark, used 1893-1984. Fineness minimum .800

Treaty countries are those countries with which France had signed commercial customs treaties. The primary basis of the customs treaty is the agreement that any duty paid on the importation of a precious metal item would be refunded to the exporter if the item was subsequently re-exported. The Netherlands was one of the treaty countries.
Check the outside of the holder perhaps somewhere in the decoration might be a maker’s mark or Dutch hallmark.
Oel.
