Actually went to the gunshop and started the law away today. Inland with Serial number 6400389. barrel is Inland dated 11-44 which seems about right. It has a Type III rear sight "I.R. Co" stamped, which appears to be correct and original, a Type III band and lug "AI" which would be original. The bore is bright and muzzle crown is crisp. Did not have a gauge or M2 ball to check, but it looks awesome. It has an Inland trigger guard (non-M2 type) with the vertical Inland stamp. The bolt is round and blued with wear, which would also be correct. The slide is a late Type V Underwood, and It has an Underwood rebuild stock with a ".U." just behind the wrist on the left side, and an X and some other letters in the sling well.
Overall finish is 95+% or better on metal, though it is not all the same color like the Koreans Blue Skies (bolt is blued). Stock is excellent, also. I did not find import marks, so possibly CMPor DCM. Came from an estate of a 90+year old, so no telling. It is the cleanest carbine my buddy has ever had in his shop, and I have known him for 10 years, and bought a few M1s through him. Best thing is the price: $850!
Seven though I had sold my carbine last year, I kept the mags, ammo (about 600 rounds), and reloading dies. I am REALLY excited.
