A dealer near me who sells lots of used rifles presently has two Krags. 

One is model 1894, serial # 11265, priced at $7xx (I forgot to write it down).  It appears mostly original, except the stock's fore end has been shortened, and the stock shows some other cuts and abuse.  I believe it has a 26 inch barrel. It seems to have the original sights.  The bore seems typical for a gun that has been fired in the era of corrosive primers. 

The other is model 1898, serial # 217908, 30-inch barrel, priced at $595.  The stock has been cut down and refinished with a relatively nice appearance.  It has a peep sight of some style I never saw before mounted at the rear of the receiver.  The peep sight prevented removing the bolt, so I could not check the bore.

Are those prices good?  Any other comments? I would appreciate any comments on whether those serial numbers are significant.  Thanks.

On the 1894 the problem sounds like the stock.  I have seen people selling forestocks that you can add and make it appear to be a full-stock again.  The barrel should be 30", if shorter then it is either a carbine (lucky you) or a cut-down rifle which would diminish its value.  I think that unless it is a genuine carbine then $7XX is about $400 too much.

On the 1898 the stock is also a problem.  If it has the original front sight and the receiver has not been drilled and tapped for the rear sight then it might be worth in the $4-$500 range depending on bore condition.  You would still need a forestock (or complete stock) plus a rear sight to make it whole.  These parts could easily cost you upwards of $300.  If the receiver has been drilled and tapped for the sight, then value just plummeted to maybe $250. 

These are just ballpark numbers based on my limited knowledge.  As 98src said photos would help, but hard to take of someone else's rifles.
