Digby Antiques (Wiltshire) has dated this piece to the Georgian era.
Silver lock to front and silver trim around edges, no marks.
The leather is in really good order for an item over 300 years old.
Please see pictures showing areas of wear to corners.

The inside is particularly good.
It opens and fastens by pushing a very small “button” on the front, up to lock down to open. It does stay closed, but if you shake it quite hard the lock will slip down and will open. This is just for accuracy.
