I'm seeking some information for a friend with this question.
It's a silver painted box with both inside and outside marks:

The outside marks are '800' and 'VM'.

The inside marks, struck centrally on the base, are a 'G800F', the 'G' and the 'F' being aligned sideways within the mark. Perhaps this is not a maker's mark, but hopefully an assay mark.

Any thoughts on this one? Maker, country of origin, any information appreciated.
