I have a Carbine that my father traded for about 45/50 years ago. It has an IBM knurled barrel with no bayonet lug, and has a black/rosy tinted finish instead of a parker finish and matching numbers.

I took it to a couple of long-time gunsmiths for their evaluation about thirty years ago and one said it was probably an early build and the other said the US exported some to Sweden with that bluing because of the Swedishicon Government specs.

I don't remember seeing any European style markings that would indicate that, but it has been a long time since I broke it down and inspected it.

Even though he gave it to me almost 35 years ago, I keep it at my father's home because he still likes to take it outside on his farm occasionally and shoot it. He is 90 and carried a similar weapon in the Pacific and now he wants me to bring it back to my home which has made me start to want to research it's history.

Any links or even guesses are welcome.

Thanks
