Inherited 1903

I inherited this 1903 after my Father-In-Laws passing and unfortunately have no information on how he came to be in possession of it.
Researching it is exhausting. I don't see any markings on the stock like other rifles posted other than that flaming cannon ball in picture number nine. .
I have had it cleaned and inspected at a local gun shop. They were quite impressed with it and said it was completely safe to fire.
I am reaching out to you Subject Matter Experts for any information you can provide. Please give me your run down.
Thanks

June, 1942 receiver with correct May, 1942 barrel. The cutoff is a replacement. Most parts look correct, although couldn't see much about the bolt.

Thanks,
How can you tell it is a replacement part?
Should I post more pictures of the bolt assembly?
Why is there no markings on the stock like others rifles? Is that common?

Yes please post more pics it is always helpful. Really nice looking rifle.

You can tell the mag cutoff is a replacement because there is no "R", for Remington, stamped on the spindle arm. Your upper and middle barrel bands should also have an "R" stamped on the right side.

Not sure about the stock might be a replacement. Funny thing is I saw a C stock about a week ago, at a local gun shop, with the same flaming cannon ball at the end of the stock.

stock may have had markings, but looks like it was beat a little in the area that would have been marked. some Kroil will help with the surface rust on the exposed metal
