The French M1822 Light Cavalry and Artillery Sabre.

Would you mind to upload a picture of your scabbard field blackening? Mine was very dark brown, I took it for rust and patina as it came off quite easily, although now I may regret that slightly...oopsy

If I remember correctly, yours was made in 1877 right? Mine is 1876.

Here it is. Not sure what the black colour is, but it is uniform across the sword. Could be rust or mystery treatment. Also no sign of second scabbard ring

i found a d'armes de Saint-Étienne Sword belong to a Great Marshal but we don't his name During French Occupation to Syria

he give it as a gift for a big "Shaikh" ( l public leader of a big tripe in Syria

there is a number printed there
its 410 the serial number of this Sword i guess 
from the 3rd republic 

flat fuller termination is early production, mostly klingenthal
full fuller is later production, mostly chatellerault

Upon closer reading and a little poking around, I think the photo caption should read:

"Center: up untill 1850; Right: before 1860 (Here you can also see the tang is slightly more straight); and Left: after 1860."

As always, I’m happy to be corrected.

I haven’t looked at this in a while; I’ll try to retrace my pokings-around. I clearly remember that none of my sources would be considered scholarly. I think I mostly looked at examples for sale or show online.

For example:

Oldswords noted that the rounded fuller end was characteristic of post-1860 examples:

The spine of my 1822 dated it to 1824. It has the straight fuller termination with a narrow ricasso.

Again, though, I’m willing to be corrected.

I have lifted the picture + text from l'Hoste.
The examples bear this out.
Early Klingenthal M1822 had almost no ricasso as seen in A. Just a little sticks out from under the washer.
B is the intermediate, which is the slightly curved ricasso shown on my Chatellerault from 1843. With curved is meant not its edge with the blade, but the contour of the ricasso that follows the contour of the blade. It is slightly bulbous over the width. ()
This is the form used up to 1860 according to l'Hoste.
After 1860 there is the flat plate ricasso.
There may be slight differences between Klingenthal and Chatellerault( After 1836) Troopers versions, but this is the general rule, which seems to be reflected by reality.
I do not see the problem.

The Ebay 1828 fits A. The washer is missing.

I stopped reading the Oldsword PDF as they, in Photo 3, think there is a Bancal in there. Those, as far as I can see, are all M1822 Troopers. The Bancal has three side bars and a much longer blade than the M1822. Oldswords is nice when one does an image search for an unknown sabre.
Text information is often not very accurate though since the contend is not curated at all.
Most of it is uploaded by sellers, not scholars.

Your M1822/24 also fits the l'Hoste pattern. This is a solid type A.

Cheers.

Edit: Now, on second read, I see the confusion.
Somehow ,,fuller termination'' crept in. Though that also changes over time, the l'Hoste figure is about the length and the form of the ricasso.

Excellent - I like the canvas cover!

A little late, but I still want to show it.

Sabre d Officier de Cavalerie légère Modèle 1822 
for artillery officers with the designation Mle 1822-1899

The blade inscription:
Manufacture nationale d'armes de Chatellerault Mai 1916 - Offer d'Artrie Mle 1822-99

Noteworthy on the scabbard are the mouth plate and the tractor. Both are made of non-magnetic material. I suspect Maillechort (Neusilber, German nickel silver).
