I recently purchased a Mosin Nagant. I'm both new to this forum as well as owning firearms and would like any assistance or guidance towards taking a step in the right direction for discovering the history of this firearm. As you could see in the pictures, the serial # I'm seeing repeated on separate parts is 9971. With that I've been able to find where this firearm was manufactured and, of course, when; however, I haven't been able to get any information more specific than that. If possible I would like to know who possessed this firearm in the past and where it might have been. I understand if that's not realistic but I thought it might still be worth asking those with significantly more knowledge on the topic than to just assume it isn't feasible. Any help would be greatly appreciated! Thank you.
