European Officers Mining Officers Sword?

[Cathey]

Hi Guys

I am in the process of researching an early English Artificers sword, when I came across a similar sword all be it a little latter that belongs to a friend of mine.

I am hoping someone can give us both more information of what they think this latter sword is and where it comes from. It looks like the second set of dates on the scabbard have been added much latter and there is also a name that has been scratched into the blade at some point. On one of the pictures, I show my older English Version along side this one for comparison.

I don’t recognise the crest which is on the scabbard and the blade either.

Any assistance will be most welcome.
