What a beautiful specimen!
Supposedly the best example of M1 rifles (if you can own only one) is a 1942 Springfield before wartime production demand pushed for as many rifles as they could deliver.
With a new Criterion you have what many would consider the equivalent of a depot overhaul rifle, with excellent condition original stock (the stamps and cartouches are beautiful).
Not so much premium collector value, rather you have a solid shooter anyone would envy, either to fire, admire, or both.
Being sentimental about the old barrel and stock is nice, but they have minimal value unless you just want to store and keep them. When it received its first depot re-build (with the 44 barrel) normally all weapons were inspected and completely stripped, all serviceable-usable components going into working bins (not kept together with original receivers) and re-assembled once worn or unserviceable parts were identified, thrown-out, and replaced.
Would kind of be like going to a garage with your truck and holding on to worn-out shocks, just to have the OEM parts.
