Hi, i have just purchased a nice exanple, comple with original sling. Some making questions please and is what is the correct model term for this rifle as it has a 5 shot mag extension. The markings are St. Etienne Mle 1907 15 on the r/h of reciever.The letter N on top of the reciever.The serial number is the same on the butt as the barrel, but different numbers on bolt and trigger guard. Im lead to believe this is quite the norm for French rifles. Thanks.
