Hello all, I'm new to the forum.  I inherited a Krag from my grandfather.  I believe he purchased at some point between WWII and Korea (USMC).  He left some shooting notes in the trap door in the butt-stock indicating he shot it in the early 50's.  In all the time I'd known him, he was a pistol shooter and it was a safe queen.   

Some info:
- On the receiver it says "Model 1898.  US Springfield Armory 462029"
- Behind the trigger guard there is a cartouche.  I can't make out the letter.  Maybe an A or a D, maybe something else.
- There is a U stamped on the barrel band.
- Under the bolt on the left side there is a cartouche that says, "JSA 1903"

I took several pictures and was hoping y'alls could help me identify what I've got, and perhaps a rough idea of its value? No intention to sell it, but simply interested to know. 

Also, where may I find information about field stripping it, cleaning, etc.?

Much appreciated!
