Any help with these koummyas?

[Kubur]

Ok I can tell you a lot about this koummiya because I have one similar and I did some researches about it. There are from the first part of the 20th c.
around 1900-1930.
Some have good and fonctionnal blades, like yours.
Some like mine have shitty blades, not even sharpened, but with a nice stamp on it. The second type is clearly for parade and are not functionnal.
They could be old tourist pieces, but I think there were just ornaments for locals.
They did some "tourist pistols" or "fantasia pistols" with the same camel bones...
