Nice old sporter!
Yup, you have an uncut barrel and the front sight ramp, although the blade is modified, is the original ramp too.
Your carbine isn't that too far gone to bring back.
I see somebody got creative with the woodwork. But that is how it was back then when these were dirt cheap surplus and some people didn't have a lot of money, but they had time to hand work stuff.
All the important expensive bits that go missing are already there for the restoration (bolt, mag, trigger guard). All you need is a full set of wood, with nose cap, barrel band and retainer. A rear sight, bolt dust cover, a bit of plug welding and lots of TLC. Sounds easy, eh?
Might be worth considering as it is all number matching. Parts can be replaced, but those drilled holes hurt it.
Or,
Leave it as a dandy little deer/Moose/bear gun and enjoy as it is..
For a good restore, the receiver could be changed, but that would be defeating the point of having all matching numbers. I don't know just what I would do. I would probably just remount a target sight and make pretty.
