Here is small item in silver (height : 4.3 cm, width : 2.2 cm).

The only mark :
a swan in an oval : French mark for items from abroad with a fineness of 800/1000 at least, 1893-1970
According to me, it was made probably between 1760-1800, and probably in French countryside (old French objects with no marks could sometimes be later marked with a swan, as if they were from abroad), or Belgian or German.
I do not known the use of such an object :
- Is it a snuff box ? It seems a bit smal for this use according to me
- Is is a snuff used for powder for gun during travel/hunting ?
- Is is a box for spices (pepper...) used druing travels ?
Let me know your advices...
Thanks
