Since it was one of the very last made, (late 43 - maybe early 44) it might not have gone through refurb unless it has been parkerized. That the stock doesn't match the barrel is not uncommon - it could have been changed post-war or even after-market by a former owner. We will probably never know which.
To nail down refurb, look for a star stamped on the top tang where the bolt rides. I'm guessing you won't find one.
Franchi marked examples are not common - you see his name mostly on 8mm conversions. It's the same Franchi name as the company that makes shotguns today.
Yours was made at the Gardone, V.T. arsenal. Late in the war, guns were only marked with serial numbers & in a few cases, not even those.
And since I have OCD, I did change spelling in your post title. The word you used related to Christianity. My bad!
