1903 Springfield Rebuild Questions

[Midmichigun]

John,
No go on the B, on the outside floorplate. However, I do have a "3" on the inside of the plate:


On the magwell/ trigger housing, I dont see any clear ID marks. I "think" I may see something that appears to be an "0" right next to the floorplate release.

It is rather small, and not clear. Sorry that I couldn't get a more clear photo. But should there be a 0 in this region?

Next question:
What is the correct buttplate for a Remington stock of this nature? I have a smooth buttplate (missing the door). Should it be smooth?


On to the stock!
I did some cleaning as mentioned. I don't believe in severe sanding, in hopes of finding marks...

What inspector marks should be on a Remy stock in this area? You can also see the cutoff has left indents in the cutout.
