Thank you so very much guys for your nice words. I really appreciate it.
I was thinking to show some more pictures of this khanjar. Unfortunately, I think the sellers pictures are better than mine.... 
 
I can say that it is a big difference to collect these kind of blades than to collect old Winchester & Marlin lever guns and Colt SAA revolvers. 
For me, I think it is hard to see if the blade come from Turkey, Iraq or Syria.... Hopefully I will learn because I think it is really interesting with the Islamic blades. 
Her comes some pictures:
