Silver gilded snuff box faded hallmark

[oel]

Dear Forum,
Due to massive construction work freeshare photo site an other photo site.

Does anybody know the origin, age and perhaps the maker of this silver gilded snuff box?
The rim of the lid reveals under a triplet the French "Swan” mark which has been used since 1st July, 1883 struck on articles coming from non-contracting countries. In addition it is struck on silverware of the legal standard of fineness, but of unknown origin, which is sold at public auctions. The rim of the box and lid reveal under a triplet also the Dutch Import Mark (.Z.) for .800 fineness. This mark has been introduced on 1st September, 1953
on the back a faded hallmark H (in oval)

I welcome all comment. Thank you

Regards,
Oel

Update: The Swan mark is not the French but German city mark for Zwickau Saxony. Herewith some new links to view pictures:
