As Del said, they can run the gamut. I have seen early carbines which were rebuilt before the Navy got them go for $ 1,250 to $ 1,400. They are refinished and all mixed parts.
I have seen original finish, late Inland and Winchester "white bag" carbines go for $ 2,400 to $ 2,500. These are the closest thing to an "As Issued" carbine many people will ever see. With the "New" Inlands going close to $ 1,000, getting a real WWII carbine in like new condition, put into storage in 1953, is worth it to me. IN A NORMAL WORLD, THESE WOULD NOT EXIST. I was around when the Civil War guns turned a hundred. Anybody ever see a Civil War gun which was not used in the war and put in storage in 1873? I wonder how many 10K dollars it would go for? More than one I bet. In not so many years, these will turn a hundred. How many of you will just have "junkers" and "shooters" and not have one "like new", been in storage for a hundred years. I can't think that far ahead.
At $2,500, these are cheap.
