unidentified marks on a Tastevin

[populous38]

Hi guys
I can't identify these marks on a Tastevin. I don't know the country.
One mark looks like '100', I'm not sure of the second mark.
Help always appreciated.

Your tastevin probably not solid silver but (French) silver-plated.
For the number 100 or perhaps 10G see:
