AS Faulkner said, $600, to $700. would be fair, but Carbines are rapidly raising in value and depending on where you are in the country,I am seeing them go for quite a bit higher than that.
Yeah, with a more in depth look at this one it might go for a little more too, it's in very nice condition. I pulled out a couple of reference books for a little closer look at the pictures.
IF the barrel is an INLAND and dated close to the receivers serial number that'll help the value to collectors.
Inland started using round bolts interchangebly with flat bolts around serial number 5,000,000. If this one is a INLAND marked bolt that could help increase the value to collectors.
If the trigger group is all INLAND that could help increase the value to collectors.
The barrel band is not likely original, Inland didn't switch over to the Type III until about serial number 6,300,000.
The adjustable stamped rear sight is not likely original, Inland didn't start using this sight until about serial number 6,200,000.
The slide is a Type III or IV and Inland started using Type V around serial number 3,000,000. A INLAND marked Type V or VI on it would increase the value to collectors. On a shooter carbine, I actually perfer a Type IV.
The stock recoil plate appears to be WINCHESTER marked.
I've already commented on the stock, but by around 5,500,000 Inland had changed from the 2 rivet to the 4 rivet handguards. If I were examining it closely I'd look to see if it is INLAND marked or not even though it's a 2 rivet type.
On closer examination, and still without actually holding it, I'll stick to my original price range estimate. You have a USGI carbine produced during the middle of Inland's production run that has been through a post war upgrade. It is in very nice condition.
What's interesting, and actually kind of a shame, but I could strip that carbine down and sell the parts on eBay or GunBroker for a sum total of about $1,200-$1,300.
