West African saber?

[blue lander]

I was oiling the blade up when I noticed the guard felt quite loose. I applied the slightest amount of pressure and the guard separated in two, revealing the base of the blade. It does appear to have a very small ricasso, although I still don't see any identifying marks. I'm going to clean the exposed part of the blade with mineral oil to see if anything pops out before I re attach the top of the guard.
