Presentation, and a sword for your appreciation

[Yvain]

The very simple and robust construction, and the serial number punched on the guard points towards a military issue.

That's what I thought, but I'm unable to find any military that used this kind of swords. The only close one I found was from a closed auction and was described as practical fighting vietnamese guom from 1887 (see picture). Almost looks like the design was taken from this for my sword and made into a military saber, but again, can't find any army sword matching this one.

Thanks for the answers anyway !
