Unusual Quaddara

If the rust has already penetrated under the koftgari, then these areas of the koftgari can no longer be saved.
So just lubricate with oil and stop the active rust.

No one is surprised by the presence of varying degrees of rust on the blade and the perfect preservation of the horn handle?

I would very much like to see a high-quality photo (high-quality - this means a sharpness high-definition photo) of the entire blade and a separate photo of point.

Hmmm.... now that you are saying....

The photos are very poor quality but I find surprising the fairly pristine condition of the cutting edge, relative to the koftgari area. Usually, the proximity of the cutting edge and mostly the tip of the blade (that is usually inside the chape) are the most affected by pitting.

I also find interesting how even the rust is on the koftgari areas.

But I am known to be on the paranoid side...

I think it's fine, look at the metal parts of the hilt, they look similar and rusted as well. Just bad photos... Nice stuff BTW

PS: Yet despite the bad photos and interesting rust distribution, I am inclined to believe it is a genuine antique piece.

I often used ''gentle'' acids like regular coke for remove rust and keep a nice patina , the koftgari isn't damaged.
a solution with diluted ferric chlorid works too.
vinegar is ok but, as mentioned, often the steel turns dull...

on the other side of the PH scale, baking soda is ok to turn rust over and preserve silver or golden koftgari
,only problem: sometimes it cleans and shine too much. and all patina is lost...

PS: I do that when the kofgari is no more visible and covered by rust, In your case,I find too its ok so just a little oil/''magic''WD40
will be good if you are afraid to lose some kofgari or aged patina...

Marius,
I did not go into explanations of the obvious: the edge was cleaned. There was no koftgari there and there were no technical limitations
As I mentioned earlier, I have used fine sandpaper on the fullers,

Francantolin,
I am intrigued by your techniques of coke and soda. Can you elaborate?

I apologize in advance. What I post in this comment is just an opinion. So everyone can continue to think as they want

Two replies from the Russian forum, where I posted photos of the "unique quadarra":

1) All metal parts including the blade are aged with acid. You will never find a struck mark of same shape on original item.

2) On a note to "expert": if you see such incomprehensible garbage, then feel free to write "Syria", there they will make "any whim for his money" for the buyer
