Hi,
The mark on the upper left is the "Poincon de charge" for small works between 1-10 1756 and 1-10 1762 (assaymaster Eloy Brichard). The mark low left is indeed the "Poincon de decharge" for small works used between 1-10 1762 and 1-10 1768 (assaymaster Jean-Jacques Prevost). So this box was made before 1762 and finished in or after 1762. The mark under right is probably the "Poincon de decharge for bigger works, a rose ((Jean-Jacques Prevost). The mark upright is worn. Maybe with a better photo we can identify the master?
