Here are the stamps that are on the outside of the stock

And another view of the area where there should be a cartouche.  Again, I don't see any evidence there was one present.

How far down would the stock have to be sanded to remove any evidence of a cartouche?  .020"? .050"?  That's quite a bit, and I'd expect that'd be noticeable.  So here's a measurement of the width, and perhaps someone with an unsanded Krag can compare.  That's about 1.590" if you can't read a dial indicator. ;)

And here's a view of the buttstock looking down.  It definitely does not have the look of a heavily sanded stock.  If it is sanded, they did a good job, did it a long time ago, and kept good care of the rifle afterwards.

So after taking these photos, I continued to strip the rifle down to its basic components to clean.  Got it all cleaned up and...  the power went out!  While I'm in the basement with no windows.  (Found out later someone had hit a telephone pole up the highway).

So I ended up putting it back together with just the light of my iPhone to show me what was going on...without instructions which I had been displaying on my computer screen down there.  I was able to do this successfully, so I'd say it's a rather simple rifle to assemble and disassemble, but the intricacies of the Krag components are a heck of a lot of fun.
