All #'s matching. I got this one from a retired Marine Corps Master Sergeant - former owner of Liberty Firearms in Beaumont, CA. He told me that it was one of two that he duffle-bagged to CONUS after his second tour in RVN in 1970. I call it "OG" because it's the FIRST SKS that I owned. Be glad to post more pics if there's any specific areas of interest. The rear sight has the Cyrillic P stamping.
