Probably arsenal refurbed or possibly re-stocked by a previous owner. The stock has all late features: low wood, 4 rivet handguard, oval sling cutout. Other late features are the rotary safety (not push button), stamped rear sight. It's surprising that they didn't update the barrel band in the refurb, which is why I question if it was done by a private owner. It also has a Winchester recoil plate (W), which it wouldn't have had coming off the Inland line. Does it have a P on the front side of the pistol grip indicative of a refurb (a P on the bottom of the pistol grip is just a proof mark). Refurbs aren't bad in my opinion, just not a top dollar all-correct carbine. The cartouche looks a bit worn, could be a light strike or worn but also look for signs of sanding. Who is the barrel maker? Should be on top just behind the front sight, often (but not always) with a month and year stamp as well. Given the date ranges for this Inland SN block, the barrel date can help you determine if it is likely the original barrel or not. An Inland stock would most commonly be marked OI in the inlet for the sling on the left side.
Given the refurbishment, I'd call it a shooter and I'd be mostly concerned with the bore and other functions. The Inland being the most common manufacturer of carbines, I would say $600-700 (with a little wiggle on either end) for a shooter grade Inland with a good bore.
Also, I own a grand total of one shooter M1 carbine, so take my "expert" advice with a grain of salt
I think they're fun to shoot and rich in history.
