Help with some hallmarks

Hello,
I have a pipe tamper modeled as a cow and it is hallmarked with 800 and a makers mark I guess german. This could be a pre 1760 british mark? Many thanks guys!

If it says 800 then it can’t be British as this was not a legally-allowed silver standard. It could be a Hanau manufacturer’s mark, but I have been unable to find a match.

Thank you for the answer. I supposed to be a hanau mark, but couldn’t find a match.
