The stock dates are usually a year earlier to allow them to dry. Three years is a long stretch but they may not have been in much of a rush with the war over and no outside threats. Does the bayonet match?
These are my favorite series of rifles and I almost didn't buy one because they weren't involved in the wars. Once I got one, the others quickly followed. K11, 1911. All are great shooters. Ammo is still available and cheap compared to most everything else out there right now.
