That is a handsome 1896 carbine with a lot of things correct about it.

Krag #34428 was manufactured around June, 1896. The number is in the carbine serial number range.

IMO - The biggest mystery is the presence of a 'cartouche' (dated 1896) with the absence of a sling-bar.

(A model 1896 carbine stock variation, that lacks the sling-bar, was used on some 1896 carbines that were rebuilt. As others have said, this replacement stock normally also lacks a 'cartouche').

Definitely, a carbine worthy of study. I hope Dick Hosmer and other 1896 carbine pros "sound-in" on this one!

My eyes may deceive me. Is this an early "thin wrist" stock? It will be interesting if it has two, rather than three, cleaning rod holes in the 'butt-trap'.

If the metal has been re-finished, it is possibly Armory/arsenal work.

The front-sight blade is a commercial replacement. A good replica is available from S&S Firearms.

It appears the muzzle 'crown' area may have been 'touched up' a bit with a file?
