Late 18th Century Box, Mezieres

[Granmaa]

Does anyone recognise these marks on what looks to me like a late 18th century French box? The lid is marked with a canon, the main box is marked with the same canon (worn) and two marks I can't make out. There is a similar canon mark in Tardy attributed to Mezieres.

Perhaps the bottom mark is the date?
