I'd been looking for an all matched original Russian-made Imperial Nagant for some time, but as we know, they are very tough to find. I was fortunate enough to find this one which definitely filled the gap in my collection. The only "upgrade" that I believe it received was the 1909 rear site. Every part except for the rear site leaf and slider has the Sestroretsk arrow on in. Rifle is duffle-cut, so undoubtedly a WWI or WWII bring-back by a US GI. Enjoy!
