This is a rarer not sporterized carbine length I.G. Mod 71/84. There were not as many of the carbine length made. This is all matching. Even the screws include 2 digits of the serial number.  Do your research on Gunbroker please. Open to all trades. I am a home based ffl so you have to be 18+, pass a background check and be prepared to pay tax. Thank you REDACTED
