Nice get. I love mine too. It's a fairly early 5 digit SN with all USGI parts. I keep threatening to put an Ultimak rail on it so I can mount a Micro T-1 RD sight but haven't yet. I have some nice wood for it but I keep a Viet Nam era GI issue fiberglass stock on it. It's ugly but tough as nails and isn't affected by moisture etc. Bevo has a nice one he hunts with
