I can see there is some loss since the fuller ends near the tip.
Could this be a sword bayonet blade? I say this because of the inspection markings which you don't see on infantry sword blades unless a sergeants sword but then only one or two marks.
What is the blade length?

I’m traveling currently, once I arrive home I’ll post some more pics

The blade length is approximately 73 CM
