Help with french sword identification

Picture of the whole sword, please. Might be interesting to see the tip, etc.

What you have here is one of the earlier nonregulation "North African" or "Chasseurs d'Afrique" or Spahi... sabres used by the North African Colonial French Forces. Later models had 3 bars and I will attach some photos.



The 2 pages are from Jean Ondry's book on French Sabres of the 2nd Empire pt 2. The others are my photos including another example I just won at auction. These, per Ondry, are relatively rare although most of them are rarer than general 1882s to begin with and very hard to detect. 



In my opinion, these wider bladed ones feel so much better in the hand, even for thrusting, that I am perpetually baffled why the fire poker of the 1882 was allowed to be adopted? As they (the pre-1882 model blades) are, even without modification, probably my favorite handling blade and IMO the ultimate spadroon type of Thrust-and-Cut feel in the hand.



Here is a comparison. On the left is a normal 1882. In the middle is a later (relatively speaking) version of your blade type. On the right is one of my favorite sabres I own, a behemoth that feels like a beautifully balanced longsword with a sabre grip. All three are of the Z shaped blade with offset fullers. The middle weighs about 765 grams and handles like a dream, the right is 950 grams but still handles beautifully due to the distal taper. As you can see by the comparison, the 1882 has little to no taper which drastically changes how it feels in the hand.

Very comparable to Field Officer grade nonregulation Highland Officer's sabres in which a lightened claymore blade is affixed to a sabre hilt. I love this general grouping of sabres so much and still for the life of me cannot understand why the 1882 was given such a dead feeling and narrower blade that makes it quite literally worse at every possible task. 

Amazing. Thanks so much for the help and the detailed answer jimmy. I will try andbget hold of that book for myself, too!
