Afghan "Khyber" knives for identification

[erikscollectables]

Added these two to my collection today. My knowledge mainly is concerned to Indonesian weapons but I started reading a lot here on the forum.

My assessment based on what I found on the forum so far:
-both so called "Khyber" knives from Afghanistan
-probably mid to late 19th century (2nd Afhan War?)
-camel bone handle and horn handle
-both seem to have reasonable quality layered steel, maybe even wootz
-the one with copper details may be from the Balloochi/Baluchi region?

Hope you guys can chime in and add some info!

Are there good period photo's around of these type of weapons being worn?
