Looks like the French 1931 artillery sword (or "artillery
gladius"). The soldiers called it coupe-choux, or cabbage-cutter. It basically a double-edged machete for clearing scrub (to have space and/or vision for artillery).

The French 1831 usually (always?) has a ricasso, and I can't see it in your photos. So this sword might be some other country's similar sword.
The British used a similar sword (sometimes single-edged, sometimes double-edged):

Then, the Russian 1848, on the right in the attached plate, from A. N. Kulinsky, European Edged and Staff Weapons. (The English-language back cover actually says "European Edged End Staff Weapons", so a search for that might find the book too.)
