Picked up this 91/30 not too long ago. Was cleaning it and noticed that the date on the tang and the barrel don't match. 1936r stamped tang, and 1937r stamped barrel. My guess that the receiver was held over for whatever reason until the next year and mated to a 37 barrel. And guess why that would be? I don't imagine it would take very long to make a mosin from start to finish, so why would it be held? Any insight would be greatly appreciated!
