i agree with these guys. It IS a Korea Vietnam era M1 carbine. General Norman Schwarzkopf of Desert Storm fame, carried an M2 Carbine in an M1A1 stock as a young Lt. in Vietnam. My 6 digit Inland is correct, though not correct for 1942. It is correct for when it was rebuilt in the 1950s, and stuck in a VCI "white bag." It has arsenal upgrades to make it a better weapon: adjustable rear sight, M2 magazine catch, Type III barrel band for better accuracy and use of a bayonet, non-dog-leg hammer, and a stronger Potbelly stock (though I added that). A restored Inland, will always be just restored. It is actually more authentic with the upgrades, because that was its last "as issued" condition.
