There is quite a division amongst carbine owners re shooters vs. collectors in regard to value.
The carbines that haven't been re-arsenaled definitely have more value from a collectors point of view. But from a shooters perspective, and that'd be me, the original flip sights are next to worthless (Who carries a hammer and punch around with them so they can correct windage??)and the Type I and II barrel bands aren't as conducive to good accuracy as are the Type III (bayonet lug)bands, especially if one is shooting with a sling. My Midway Carbine came with what I understand to be a "highly collectible" Winchester dog-leg style hammer. They tell me that this hammer is largely responsible for the atrocious 9 lb. trigger pull, but that I'd be a fool to change it because its original to the trigger housing.
So it's arguably more valuable but more difficult to shoot!
Carbines that have been re-arsenaled, on the other hand, have been checked out and had the appropriate parts upgraded to newer parts and parts that are out of spec replaced, making them more reliable, giving them longer shooting life and making them more valuable to those of us who like to shoot what we own.
