Oh crap, I'm tottaly wrong. I figured someone already had checked the SRS on the serial, so I didn't check that list. I was just running the serial off my Marine one.
Ed is 100% right. It has a DCM sales hit. So it was just a commercial sale before the war. It wouldn't have had anything to do with the Marines.
It's neat though it's so close. My buddies rifle is 17 digits away from yours and I'm sure he would still love to see pics of your rifle. His has a 12-36 SA star guaged barrel as well.
Are you sure your rifle is re-conditioned? It was sold pretty quick after it was built. But now you have a 100% documented NM rifle. In the old days of the SRS, you could get a letter and see who your rifle was actually sold to. But I don't know if they do that anymore, as far as provide the name of the guy the rifle was sold to.
