Here's some pics and details: s/n 341xxxx puts it in the correct range for 1943 production and the "split bridge" markings along with the bolt and scope mount were what I went by to satisfy myself it was the real deal.
Good so far, but there's a few issues: barrel cut back about 1.5" (this is the only real issue as I see it, and it can be overcome just will require a gunsmith and time to hunt down an appropriate barrel. Barrel dated 7-43,
but as I understand a 7,8, or 9-43 barrel would be OK too. The stock has been chopped and needs replacing. And it needs a scope and rings. The whole thing has a uniform dull blue appearance to it.

1. If I can't find a "correct" NOS barrel, can a barrel be removed from a 1903A3 and be used without any issue aside from removing the front sight base. NOW HOLD ON THERE, I'm not advocating the destruction of another good rifle. I found a National Ordnance 1903A3, which is a commercial rifle, that has a Remington barrel that looks nice. I could put a repro barrel back on the NO rifle and it wouldn't hurt the value of it.
2. Will a 1903 scant stock fit this? Correct? It appears to have a been a point of some debate.

I live not far from Anniston and plan on letting CMPicon do the rebarreling as it would seem they should know what they are doing.
