Thank you for the information. I couldn't find that patch for any of the units that fought in the Philippines in 1945. Do you think the gun went to the Philippines after the Korean war or as I thought might have gone to the Philippines from the manufacturer in 1945?

Bob,

I don't see any marking at all in the sling well. The front sight has an "R" very small, behind the sight blade. Mag Catch looks like it has and "HI" or "IH". Looks like an "N" on the bottom of the safety lever, but partially obscured. It does have the hand stamped "1" at the front of the receiver right after the"30 M".
