Golden box

[huszas76]

Hello All!
Today I saw a box. Unfortunatly can't make any picture about the item (maybe later) just only the marks. Can anyone help me to identify?
This one is (if I'm not wrong) an import mark from Netherland between 1831-1893 for precious metals:

There was another marks. This one (maybe the maker?):

And another one for the fineness:

But here is another one fineness number (800) and (maybe) a serial number.

Thank you very mach any help!
Best regards!

Hello Everybody!
When I was settling my old photos in my computer, I found an interesting, similar mark in a 19. century gold Vacheron Constantin pocket watch:

I think, it could be a promising clue!
Maybe the box made in Switzerland, by the same maker? Or the G means a gold mark for Geneve? Anyone has any knowledge to the gold marks in the 19. century in Switzerland, especially for Geneve?
Thank you very much any comments in this case!
Best regards!
