Lots of history in this rifle, probably lots of people killed by the bullets guided by it's rifling that propelled by the cartridge from which it came after the primer was struck by the firing pin which was released by the trigger and the trigger finger of each person who held it.
Backstory: Czarist Russia contracted out a several million rifle and production to get arms for WWI since they didn't have enough to go around during the conflict. Of those contracts, New England Westinghouse was one, of the rifles produced for Russia few of them actually made it out to be in the war because they couldn't afford to pay for the contracted weapons.
This is one of the few that made it in time for WWI, I can't say where it went there, and I can only guess if it was used in the Bolshevik Revolution, but what I can say is that it took plenty of damage, was held by many hands, and has probably seen more bloodshed than one could ever imagine.
Captured by Finland (The Winter War):
Most likely captured in the field by Finland and back again by the Red Army when Hamina was over run by the Soviets, I can only guess that this rifle was an early Capture however.
It was most likely damaged in battle (stock splicing by the Finns tells me this), before the repairs it could have been in Soviet posession (No way to tell however) the type of D and SA mark indicate that it's probably a 1939 capture corresponding with my observations and theories on it's history. To boot, the rifle's Civil Guard number places it in Hamina, indicating it was picked up by the Soviets after battle and assimilated back in to the Red Army.
First Military's rifle, second a Revolutionaries, a Soldier's twice more, once Civilian's, and one more time a Soldier's before becoming in to my hands. I couldn't tell you everything about it exactly, but I can tell you it's seen a lot of war.
It's really a wall hangar, hell it should be a museum piece, it's not like I'd probably be able to hit accurately with it since the rear sight seems to have taken a good blow.
