I love the French history and culture, so I poke a bit of fun at them. But I do want to find at least a stock for this. From the bent bolt and the trigger guard with integrated sling swivel I believe I have a 'cavalry carbine' version. The barrel is 49cm(like an artillery musketoon), but I think it might've been cut down at some point. It was most likely last used 'officialy' in Yemen, which might explain the massive modifications to the stock. In addition, there is a groove on the right side of the barrel at about 39cm from the reciever/barrel interface, and a very faint marking of a barrel band 12-14cm from the R/B interface(5.5-7.5cm from front of rear sight base). The front sight appears to have been soldered/brazed on, and is slightly crooked. These features and the lack of any bayonet mount lends some credence to the possibility of the barrel being cut down at some point.
I removed the stock today to investigate the non-functioning trigger, and found large numbers of proof-marks on the bottom of the barrel and reciever. I'm adding those photos in the hope someone will be able to help me narrow down this weapon's history.
There appear to be several additional SNs. The "M49293" with the "FV" above it is on the left side of the barrel and reciever. On the bottom of both are the following visible SNs:
D216
E308
G86
There are several "crown above E" marks on both, and what my be a cruder "crown above L" or an arabic letter on the barrel. There is also a "Y383" on the barrel. Below the rear sight on the left side are a "M in circle" and a "J in circle" marks, and an "MA" mark under the "S.1873 C.1876" mark on the right side under the rear sight.
Ultimately there are a lot of other marks, comprising letters, numbers, and symbols. I've tried to provide pics of all.
