Thanks for the information. I bought it from a friend of the family for $80. I love this era and era of guns. I doubt that I would ever sell it, but I was told that I got a pretty good deal.The "9" above the trigger group means nothing. Someone just scratched that into the wood. Most of the weapons that the U.S. gave to South Korea were rebuilt - sometimes more than once - so the odds of having a matching M1 Carbine are slim at best. You'll want to completely disassemble your weapon and inventory what is there.
For being a Blue Sky re-import, your M1 Carbine looks pretty good. Blue Sky was never known for being picky about the quality of surplus arms that they managed to re-import. I think you did pretty well. WW2 era U.S. arms are getting scarce and pricey. If you decide to refinish your stock, go very easy on sanding to try to keep the Arsenal markings as much as possible intact and try not to round over the sharp edges. Then just a good hand rubbed linseed oil finish would do the job.
I got my Standard Catalog of Military Firearms today, and the first thing I have had the opportunity to use it for is this M1 Carbine. I found this statement about the imports - Several thousand carbines were imported from Korea in the late 1980's. These were US made guns that we gave them during the cold war. Other batches of carbines have been imported from West Germany, Israel, and other nations. All post 1986 imports will have an import stamp on the barrel or receiver. The most common are Blue Sky and Arlington Ordinance.Alpo, do you know if all Blue Sky stamped M-1's came from Korea? I want to remember I was told told some of them came from Israel, no? My Inland is a Blue Sky and the butt has the finish worn off from the web magazine pouch that was often strapped to them.
